  • Automotive virtual edge communicator (AVEC) with vehicular inter-agent
           service orchestration and resourcing (ViSOR)
    • Abstract: At time of crisis, relief teams must have assured connectivity, not only just within the team but also across different service agencies in the area. Since emergency agencies and essential services always send service cars to affected zones, advanced technologies and computing resources aboard these vehicles can be pooled together to boost network capacity temporarily, just where it is crucially needed. These vehicles become automotive virtual edge communicators (AVECs). They are managed by a vehicular inter-agency service orchestration and resourcing (ViSOR) system that creates transient proximity-based “trust circles” to manage novel cooperative hosting, opportunistic virtualization, and “car sourcing” of crisis zone data. This study evaluates the feasibility for this challenging but highly rewarding concept and identifies gaps in emerging technologies.

  • Collision avoidance in shared slots in wireless devices of the Internet of
           Things: models and simulations
    • Abstract: In this paper, we propose an analysis of a slot-based protocol designed for devices of the Internet of Things (IoT). In contrast to other TDMA-based protocols, this scheme uses a random technique to access shared slots, similarly to CSMA protocols. In practice, the transmissions are scheduled in a given backoff window of slots whose duration allows the transmission of a packet and its acknowledgment. Therefore, this protocol can be analyzed according to the methodology introduced by Bianchi for the IEEE 802.11 protocol even if the protocol studied differs in many aspects. The model we use is also particular because we succeed in obtaining a Markov model even though the scheme used to send a packet (in a node) may depend on the transmission of the previous packet. We distinguish two protocols; in the first one, at the initial stage or after a successful transmission, the packets are transmitted without any backoff, whereas in the second protocol each transmission is always preceded by the count down of a random backoff. Extensive simulations validate both protocols models. In addition, the performances of these protocols are compared with those of slotted Aloha and a protocol using a constant backoff window.

  • Discovering the right place to check-in using web-based proximate
           selection
    • Abstract: With information technology becoming increasingly embedded in our everyday physical world, there is a growing set of mobile applications that involve a connection with the digital representation of physical places. This association is normally initiated with a check-in procedure, through which a person asserts her presence at a particular place and determines the context for subsequent interactions. The common assumption is that a mobile application will be able to search the surrounding environment and present the user with the intended check-in target; however, in a world of ubiquitous place-based services, this assumption may no longer hold. A person in an urban environment would, at any moment, be surrounded by a large number of places, all of which could be regarded as possible interaction contexts for that person. In this work, we investigate the real-word challenges associated with wide-scale place selection and how the process can be affected by the place environment, by the position of the person in relation to the target place and by positioning errors. To study this reality, we used Google Places as a directory of georeferenced places. We conducted 14,400 nearby place queries structured around different combinations of our three independent variables. The results suggest that the overall performance is poor, except for low-density scenarios, and that this discovery process, albeit relevant, should always be combined with other place discovery approaches. The results also help to understand how this performance is affected by check-in positions and by the properties of the place environment.

  • Mobility support enhancement for RPL with multiple sinks
    • Abstract: In recent years, low power and lossy networks (LLNs) have attracted the attention of researchers. They typically operate with strict resource constraints in communication, computation, memory, and energy. Routing protocol for LLNs (RPL) is an ad-hoc distance vector routing protocol for LLNs that adapts IPv6 and runs on top of IEEE 802.15.4 standard. Although RPL was originally designed for static topologies, for many applications mobility support has been a major requirement in LLNs. In addition, part of these applications requires multiple sink nodes rather than one sink node. This is due to the fact that in a data collection wireless sensor network (WSN), only one sink easily leads to a faster energy depletion, more packet loss, higher latency, and smaller network range. Deploying multiple sinks in the network can help solve these problems. This paper focuses on addressing mobility support in RPL with multiple sinks. We propose an enhancement based on signal strength monitoring and rank updating in order to improve the network performance in mobility scenarios where all nodes except sink nodes are moving. This enhancement helps RPL to better cope with mobility scenarios and to make faster decisions on updating next-hop neighbors. Moreover, we propose a dynamic management of control messages in order to reduce the overhead in the network. Simulation results show that our technique outperforms the standard RPL in different network configurations.

  • Distributed scheduling with efficient collision detection for end-to-end
           delay optimization in 6TiSCH multi-hop wireless networks
    • Abstract: It is expected that the IEEE 802.15.4e-TSCH designed for wireless industrial sensor networks will be used in IoT systems. This standard relies on techniques such as channel hopping and bandwidth reservation to ensure both energy savings and reliable transmissions. Since many applications may require low end-to-end delay (e.g., alarms), we propose here a distributed algorithm to schedule the transmissions while upper bounding the end-to-end source-sink delay. Our strategy constructs stratums, regrouping all the nodes with the same depth in the DODAG Destination Oriented Directed Acyclic Graph constructed by RPL. Then, different time-frequency blocks(bands) are assigned deterministically to each stratum. By appropriately tuning the size of each block and chronologically organizing them, we are able to guarantee any packet is delivered along the path length to the border router before the end of the slotframe. We also provide self-healing mechanism to detect and alleviate local collisions. Experiments on a large-scale testbed prove the relevance of this approach to reduce the end-to-end delay while minimizing the number of collisions, prejudicial to the reliability in multihop networks.

  • Universal secret payload location identification in spatial LSB stego
           images
    • Abstract: Locating steganographic payload is an important aspect of active steganalysis which deals with finding the pixel locations of the embedded secret message (payload) in the stego image. The residual-based payload location detectors are well suited for this purpose. In this paper, an improved universal, blind method of precisely identifying locations in the spatial domain using enhanced weighted residuals with only a few known stego images is proposed. This is done by estimating the cover from the available stego image using the proposed novel locally weighted bivariate shrinkage function in the transform domain. The enhanced weighted residuals ensure that the proposed method is universally applicable for detecting payload locations in spatial least significant bit stego images. The added advantage of the proposed method is that it does not require any prior knowledge of the cover source or the embedding algorithm to determine the exact locations. Experiments conducted on five spatial LSB domain algorithms show that the payload locations can be precisely estimated with a minimum accuracy of 90% with 100 known stego images.

  • An evaluation methodology to assess the accuracy of a tracking system in
           the case of horse races description and experimental validation
    • Abstract: All sorts of positioning systems exist and there is a growing demand nowadays in order to provide users with additional data in many activities. Horse racing is no exception and the PMU (Paris Mutuel Urbain) is in charge of driving the project concerning the deployment of a tracking system. PMU is Europe’s largest betting operator. It is an Economic Interest Grouping (EIG), whose mission is to finance the French horse racing industry. The specifications of the tracking system to be implemented are quite tough: an accuracy of positioning of 25 cm for more than 98% of the time during races for all the horses. A call for proposals has been issued and a few competitors have been hired in order to demonstrate the real performances of their system in a so-called “pilot” phase. The problem we now have is how to evaluate the real accuracy of the system in real conditions, i.e., during “simulated races.” Additional aspects are also of uppermost importance, such as the latency and the way data are displayed, but the present paper will only focus on the evaluation methodology used for the positioning accuracy assessment. An incremental validation approach was set up in order to allow the competitors to gradually improve their solutions, from the “easiest” tests (with cars) to the “most difficult” ones on horses during simulated races. Note that all competitors proposed a GNSS (Global Navigation Satellite System)-based solution using an RTK (Real-Time Kinematic) approach.

  • Optimal data collection in wireless sensor networks with correlated energy
           harvesting
    • Abstract: We study the optimal data collection rate in a hybrid wireless sensor network where sensor data is collected by mobile sinks. In such networks, there is a trade-off between the cost of data collection and the timeliness of the data. We further assume that the sensor node under study harvests its energy from its environment. Such energy harvesting sensors ideally operate energy neutral, meaning that they can harvest the necessary energy to sense and transmit data, and have on-board rechargeable batteries to level out energy harvesting fluctuations. Even with batteries, fluctuations in energy harvesting can considerably affect performance, as it is not at all unlikely that a sensor node runs out of energy, and is neither able to sense nor to transmit data. The energy harvesting process also influences the cost vs. timeliness trade-off as additional data collection requires additional energy as well. To study this trade-off, we propose an analytic model for the value of the information that a sensor node brings to decision-making. We account for the timeliness of the data by discounting the value of the information at the sensor over time, we adopt the energy chunk approach (i.e. discretise the energy level) to track energy harvesting and expenditure over time, and introduce correlation in the energy harvesting process to study its influence on the optimal collection rate.

  • Measurement and security trust in WSNs: a proximity deviation based
           approach
    • Abstract: Quality of communication and measurement accuracy are of prime importance in WSN-based applications, as the sensors have to report real-time measurements to enable efficient decision-making. These sensors are often subject to measurement errors, such as noise, nonlinearity, and deviation caused by rapid changes. Sensors are prone to failures and can be targeted by attacks that aim to modify their outputs. To address these drawbacks, measurement should be checked, sensor functions should be protected, and accuracy should be analyzed all the time. In this paper, we propose a trust management framework based on three metrics: the true measurement deviation, group deviation, and security metrics to analyze the accuracy and trustworthiness of sensor data. The third metric considers the attacks detectable at the communication architecture layers. We have derived an analytical model (i) to calibrate the sensors periodically by deciding on their trustworthiness, and (ii) to modify their outputs periodically, whenever needed based on the deviation in measurement. Our simulation results for a real-time fire monitoring system show that the proposed trust framework is efficient in producing 95% accurate and trusted measurements by limiting the frequency of sensor calibrations to a minimal value and by setting a lower boundary of 5% deviation from the true and group value metrics with its added trust at the micro-level by disproving attacks at the protocol layer.

  • Dynamic Multicriteria Alternative Routing for single- and multi-service
           reservation-oriented networks and its performance
    • Abstract: We propose a new Dynamic Multicriteria Alternative Routing (DMAR) method that applies to reservation-oriented networks. DMAR combines a dynamic alternative routing scheme with a periodic update of alternative paths according to a multicriteria algorithm that aims to balance the traffic between traffic flows in single-service networks and also between services in multi-service environments. We conducted extensive simulations to compare the performance of DMAR with that of other reference alternative routing schemes in single- and multi-service networks with several topologies and load scenarios, namely with non-stationary traffic. We show that DMAR efficiently adjusts to traffic changes while often presenting better network performance than the reference alternative routing schemes, particularly in the multicriteria sense.

  • Certificateless public key encryption with conjunctive keyword search and
           its application to cloud-based reliable smart grid system
    • Abstract: A public key encryption scheme with conjunctive keyword search allows a semi-trusted third party (or a cloud server) to search over an encrypted data after receiving a trapdoor generated from a conjunctive keyword set. Assume that a sender sends a number of data to a receiver and those data are all stored in the same cloud server. Normally, if the receiver uses one keyword or separate keywords to look for through hundreds of data, it might get in return a huge number of associated data and most of them are unwanted. In this paper, we design a new certificateless public key encryption scheme with conjunctive keyword search, which only returns the desired data. We also prove that the designed scheme is secure against adaptive chosen keyword attacks in the random oracle model under bilinear Diffie-Hellman (BDH) problem assumption. Experimental results show that our scheme has better performance during the testing phase and has a lower communication cost than two related schemes. The comparison about security properties also shows that our scheme is more secure than them. Finally, we give an application example of our scheme in a cloud-based reliable smart grid system.

  • Exploiting capture and interference cancellation for uplink random
           multiple access in 5G millimeter-wave networks
    • Abstract: The forthcoming 5G technology aims to provide massive device connectivity and ultra-high capacity with reduced latency and costs. These features will be enabled by increasing the density of the base stations, using millimeter-wave (mmWave) bands, massive multiple-input multiple-output systems, and non-orthogonal multiple access techniques. The ability to support a large number of terminals in a small area is in fact a great challenge to guarantee massive access. In this context, this paper proposes a new receiver model for the uplink of 5G mmWave cellular networks. The receiver, called Iterative Decoding and Interference Cancellation (IDIC), is based on the Slotted Aloha (SA) protocol and exploits the capture effect alongside the successive IC process to resolve packet collisions. A 5G propagation scenario, modeled according to recent mmWave channel measurements, is used to compare IDIC with the widely adopted Contention Resolution Diversity SA (CRDSA) scheme to show the performance gain of IDIC, when elements of practical relevance, like imperfect cancellation and receive power diversity, are considered. The impact of packet and power diversity is also investigated to derive the preferable uplink random access strategy that maximizes the system throughput according to the offered channel load.

  • Traveling distance estimation to mitigate unnecessary handoff in mobile
           wireless networks
    • Abstract: Amidst the factors that degrade the performance of a mobile wireless network (MWN), unnecessary handoff is considered to be one of the premier culprits since it aimlessly consumes the network resources. Most of the existing handoff algorithms proposed for MWN suffer from frequent unnecessary handoff as the primary decision of switching network cells is solely based on a single contributing factor, namely the received signal strength (RSS) that approximates the distance between a mobile node and access points. In practice, the RSS may not provide accurate approximation of the true distance as it fluctuates with wireless propagation impairments (such as shadowing, scattering, and reflection), leading to potential incorrect handoff decision within neighboring cells. In this paper, an improved estimation model for instantaneous distance between the mobile node and access point is formulated. Building upon this model, a new handoff technique is proposed by introducing two RSS thresholds and estimated distance verification, anticipating RSS fluctuations that may lead to handoff decision errors. The performance of the proposed handoff mechanism is thoroughly examined using numerical simulations and the acquired results demonstrate promising advantages of this proposed technique.

  • Oblique projection-based interference suppression for MIMO power line
           communication
    • Abstract: In this paper, it is proved that in multi-conductor power line communication (PLC), spatial multiplexing can be achieved not only in different transmission modes but also in a same transmission mode, which means that spatial multiplexing technique can suppress the interference from any transmission modes. With this conclusion, a co-channel interference (CCI) suppression method based on oblique projection is proposed for multi-conductor PLC. In this method, the oblique projection operator which maps the received signal to the signal space along the interference space is estimated based on second-order statistics of the received data, and then the CCI can be suppressed by the oblique projection operator. The simulation results reveal the validity of the proposed method.

  • A high gain S-band slot antenna with MSS for CubeSat
    • Abstract: Cube satellites, aka CubeSats, are a class of tiny satellites that have become popular for space programs. This is because they can be built relatively cheaply using commercial off-the-shelf components. Moreover, CubeSats can communicate with each other, and assemble into swarms to carry out different functions: e.g., wide area measurements and sensing. Swarms of CubeSats also have the effect of increasing the contact period with ground stations allowing for a longer communications window. These capabilities require CubeSats to be equipped with an efficient, high gain, small antenna to facilitate cross-link or inter-satellite communications. Henceforth, this paper presents a high gain coplanar waveguide (CPW)–fed slot antenna for CubeSats. A key feature is the use of a metasurface superstrate structure (MSS) to significantly improve gain and reduce back-lobe emissions. This also has the advantage of minimizing interference to components inside a CubeSat. We have comprehensively evaluated the antenna using the high-frequency simulator structure (HFSS) as well as a carrying out testing on a 3 U (10 × 10 × 30 cm3) CubeSat platform. We have studied the effect of MSS element sets and their position and the effect of a 3-U CubeSat body on the performance of the proposed antenna. The experimental results confirm that our antenna achieves a return loss of 21.5 dB and a fractional impedance bandwidth (BW) of 55.91% with S11 ≤ 10 dB and has a simulated and measured gains of 9.71 and 8.8 dBi respectively at the desired frequency of 2.45 GHz. In contrast, amongst all previous S-band planar antennas that are suitable for CubeSats, the best gain is only 5.96 dB at 2.45 GHz.

  • A cooperative approach with improved performance for a global intrusion
           detection systems for internet service providers
    • Abstract: Typical perimeter-based intrusion detection systems do not provide the user with the necessary preventive protection measures. In addition, many of the available solutions still need to improve their true-positive detection rates and reduce the proportion of false-positive alarms. Therefore, internet service providers, utilising this type of device to defend their assets and subscribers against malicious traffic, may be induced by them to make incorrect decisions. In this paper, we propose a global intrusion detection system, based upon the BGP protocol that establishes a cooperative federation whose members are distributed autonomous intrusion detection elements. These elements are able to propagate alarms of potential threatening flows traversing their respective autonomous systems. We present the architecture for the described approach and an analytical model based upon Dempster-Shafer’s combination rule, in order to evaluate specific performance metrics. The results show significant improvements over the assessed metrics, highlighting the advantage of using the proposed solution as a frontline to prevent cyberattacks.

  • Capacity optimization of multi-input/multi-output relay channel by SADDE
           algorithm
    • Abstract: In this paper, we use self-adaptive dynamic differential evolution (SADDE) to search for multi-input/multi-output (MIMO) relay locations and transmitter locations to reduce the outage probability in the indoor ultra-wideband (UWB) environment. Amplify-and-forward (AF) MIMO relay is chosen to improve the performance of the environment. We use the shooting and bouncing ray/image (SBR/image) method to compute the frequency response, which is used to compute capacity. The channel capacities for the linear antenna with 1 × 1 antenna, 3  3 spaced linear antennas, and 3 × 3 tri-polarized antennas are compared. First, we deploy the relay and transmitter at the equipartition area. It is found that there are some outage receiving points. Thus, the SADDE is employed to optimize the position of the relay and transmitter in order to reduce the outage probability. Numerical results show that the outage probability for the relay and transmitter location is reduced by SADDE. Moreover, it is found that the channel capacity for the tri-polarized antennas has increased when comparing to 3 × 3 spaced linear antennas. For the zero outage probability requirement, the signal to noise for the tri-polarized antennas is lower 6 dB than that for 3 × 3 spaced linear antennas.

  • Popularity prediction–based caching in content delivery networks
    • Authors: Nesrine Ben Hassine; Pascale Minet; Dana Marinca; Dominique Barth
      Abstract: In content delivery networks (CDNs), caches are resources that must be allocated. For that purpose, videos’ popularity knowledge helps to make efficient decisions about which videos should be cached. Thus, we must be able to anticipate future needs in terms of requested videos. To do this, we rely on the requests history. This paper focuses on predicting the videos’ popularity: the daily number of requests. For that purpose, we propose a two-level prediction approach. At the first level, the experts compute the videos’ popularity, each expert using its own prediction method with its own parameters. At the second level, the forecasters select the best experts and build a prediction based on the predictions provided by these experts. The prediction accuracy is evaluated by a loss function as the discrepancy between the prediction value and the real number of requests. We use real traces extracted from YouTube to compare different prediction methods and determine the best parameter tuning for experts and forecasters. The goal is to find the best trade-off between complexity and accuracy of the prediction methods used. Finally, we apply these prediction methods to caching. Prediction methods are compared in terms of cache hit ratio and update ratio. The gain brought by this two-level prediction approach is compared with that obtained by a single prediction level. The results show that the choice of a two-level prediction approach is justified.

  • Isolation in cloud computing infrastructures: new security challenges
    • Authors: Mohammad-Mahdi Bazm; Marc Lacoste; Mario Südholt; Jean-Marc Menaud
      Abstract: Cloud computing infrastructures share hardware resources among different clients, leveraging virtualization to multiplex physical resources among several self-contained execution environments such as virtual machines or Linux containers. Isolation is a core security challenge for such a computing paradigm. It may be threatened by side-channels, created due to the sharing of physical resources like processor caches, or by mechanisms implemented in the virtualization layer. Side-channel attacks (SCAs) exploit and use such leaky channels to obtain sensitive data such as kernel information. This paper aims to clarify the nature of this threat for cloud infrastructures. Current SCAs are performed locally and exploit isolation challenges of virtualized environments to retrieve sensitive information. This paper also clarifies the concept of distributed side-channel attack (DSCA). We explore how such attacks can threaten isolation of any virtualized environments such as cloud computing infrastructures. Finally, we study a set of different applicable countermeasures for attack mitigation in cloud infrastructures.
