  • Spectrum sensing in cognitive radio using multitaper method based on
           MIMO-OFDM techniques
    • Abstract: The current inefficient utilization of frequency spectrum has alerted regulatory bodies to streamline improvements. Cognitive radio (CR) has recently received considerable attention and is widely perceived as a promising improvement tool in estimating, or equivalently sensing, the frequency spectrum for wireless communication systems. The cognitive cycle in CR systems is capable of recognizing and processing better spectrum estimation (SE) and hence promotes the efficiency of spectrum utilization. Among different SE methods, the multi-taper method (MTM) shows encouraging results. Further performance improvement in the SE for CR can be achieved by applying multiple antennas and combining techniques. This paper proposes a constructive development of SE using MTM, abbreviated as MTSE, and by employing multiple-input multiple-output (MIMO), parsed into separate parallel channels using singular value decomposition (SVD), and maximum ratio combining (MRC) configurations. Deviating from these improvements, however, multicarrier systems such as orthogonal frequency division multiplexing (OFDM) show inferior sensing performances due to the noise multiplicity generated and combined from all subcarrier channels. By means of the quadrature matrix form, the probabilities for such integrated settings of SE have been derived to reach at their approximate asymptotes. Numerical simulations revealed specific better performances stemmed from coupling the fashionable MTSE and MIMO technologies.

  • 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.

  • 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.

  • Efficient relay selection scheme utilizing superposition modulation in
           cooperative communication
    • Abstract: In this paper, a cooperative communication scheme is proposed utilizing superposition modulation (SM) in orthogonal frequency division multiplexing (OFDM). The proposed relay selection scheme selects an optimal relay and improves the BER performance by utilizing SM in cooperative communication. Also, the proposed cooperative communication scheme transmits the signal of source and relay at the same time by utilizing SM. As a result, the proposed schemes select the optimal relay and improve the reliability and throughput compared with the conventional cooperative communication scheme.

  • An optimal mutually coupled concentric circular antenna array synthesis
           using ant lion optimization
    • Abstract: This paper presents an accurate design approach for concentric circular antenna array (CCAA) synthesis to improve the far-field radiation characteristics using a meta-heuristic optimization technique called ant lion optimization (ALO). The far-field radiation pattern is improved with lower side lobe level (SLL) which is essential for the reduction of interference in the entire side lobe regions. The ALO algorithm is a recently proposed evolutionary technique which is applied to determine the optimal sets of current excitation weights and to find the optimal inter-element spacing between the array elements in the 3-ring structure of the CCAA design. In this context, the design examples of two 3-ring CCAAs, one having the set of (4, 6, 8) elements and the other having the set of (8, 10, 12) elements, with and without the centre element, are presented by optimizing the array parameters. The results obtained by using the ALO algorithm–based approach show considerable improvement of SLL with respect to that of the uniform array pattern and those of the methods reported in the recent literature.

  • Multi-carrier, multi-band, and multi-layer cellular layouts using 3D
           beamforming for 5G ultradense networks
    • Abstract: Three-dimensional (3D) beamforming and higher order sectorization (HOS) represent two fundamental features to boost the capacity of ultradense heterogeneous networks and fulfill the huge data rate requirements for next-generation mobile networks (5G). The capacity gain depends on the antenna pattern, the inter-cell interference (ICI), and the cellular layout whose design is considered as the main step in the life cycle of a cellular network. Indeed, it decides the operational expenditure (OPEX), the capital expenditure (CAPEX), and the long-term quality of service (QOS). In this paper, we propose new multi-carrier, multi-layer, and multi-band cellular layouts. By exploiting the capability of the 3D beamforming as well as the 3D channel model conceived by the third-generation partnership project (3GPP), the layouts comprise macro and virtual small cell (VSC) layers, which are planned based on geolocation data and a user-grouping algorithm. We have demonstrated that the simulation of the new proposed cellular layouts results in a significant coverage enhancement and interference mitigation, as compared to the reference cellular layout which is 3GPP case 1.

  • Traffic load–based cell selection for APCO25 conventional–based
           professional mobile radio
    • Abstract: Wireless communication between public safety officers is very important to transmit voice or data during emergency crises. When the public communication networks cannot provide services during crises, disasters, and high traffic cases, Professional or private mobile radio (PMR) such as Association of Public Safety Communications Officials (APCO25) conventional systems are needed to improve the service quality and to provide uninterrupted service to the users. In this paper, we propose traffic-based cell selection algorithms for the APCO25 conventional systems to attach users to base stations in a balanced manner to reduce waiting time while establishing a connection. The simulation results of the proposed traffic load–based cell selection algorithms are illustrated in terms of the RSSI measurements counter, the number of connection requests, the average waiting time, and the number of re-selections for the APCO25 conventional systems.

  • Space-time code selection via particle swarm optimization
    • Abstract: In this paper, the space-time code selection technique for multiple-inputs single-output systems is optimized using particle swarm optimization. We considered both variable-rate and constant-rate strategies. For a variable-rate technique, we address the problems of minimizing the bit-error rate for a given throughput objective and maximizing the throughput for a given bit-error rate objective. For a constant-rate technique, we address the problem of minimizing the bit-error rate. Results show that it is possible to find BER and throughput values close to those required when using a variable-rate technique with optimized threshold levels. For the constant-rate technique, we obtain considerable energy to noise gains when using optimized threshold levels.

  • Multi-cloud cooperative intrusion detection system: trust and fairness
           assurance
    • Abstract: The sophistication of the recent cloud computing systems has made them more vulnerable to intelligent cyber attacks. Moreover, it is becoming very difficult for a single intrusion detection system (IDS) to detect all existing attacks, due to limited knowledge about such attacks’ patterns and implications. Recent works in cloud security have shown that cooperation among cloud-based IDSs can enhance their accuracy. However, there are two main challenges associated with the existing cooperative IDSs, which are related to trust and fairness assurance. To tackle these challenges, we propose in this paper a cooperative cloud-based IDS framework that (1) enables IDSs to distributively form trustworthy IDSs communities by advancing a trust-based hedonic coalitional game, which allows IDSs to increase their individual detection accuracy in the presence of untrusted IDSs and (2) formulates a fairness assurance mechanism as a Stackelberg game between the well-behaving IDSs and the selfish ones that frequently send consultation requests to other IDSs, and at the same do not answer other IDSs’ consultation requests. Experimental results show the effectiveness of the proposed approach in terms of enhancing the accuracy of detection and achieving the fairness among IDSs in terms of benefits obtained through cooperation.

  • Algorithms for the design of 5G networks with VNF-based Reusable
           Functional Blocks
    • Abstract: We face the problem of designing a 5G network composed of Virtual Network Function (VNF)-based entities, called Reusable Functional Blocks (RFBs). RFBs provide a high level of flexibility and scalability, which are recognized as core functions for the deployment of the forthcoming 5G technology. Moreover, the RFBs can be run on different HardWare (HW) and SoftWare (SW) execution environments located in 5G nodes, in line with the current trend of network softwarization. After overviewing the considered RFB-based 5G network architecture, we formulate the problem of minimizing the total costs of a 5G network composed of RFBs and physical 5G nodes. Since the presented problem is NP-Hard, we derive two algorithms, called SFDA and 5G-PCDA, to tackle it. We then consider a set of scenarios located in the city of San Francisco, where the positions of the users and the set of candidate sites to host 5G nodes have been derived from the WeFi app. Our results clearly show the trade-offs that emerge between (i) the total costs incurred by the installation of the 5G equipment, (ii) the percentage of users that are served, and (iii) the minimum downlink traffic provided to the users.

  • Resource management of cloud-enabled systems using model-free
           reinforcement learning
    • Abstract: The digital system of the future will face the growing challenge of controlling the system behavior in complex dynamically evolving environments. In this paper, we examine the applicability of a new management paradigm based on a reinforcement learning approach, where no preliminary specification of the system model is required. The learning agent identifies the most adequate control policies in live interaction with a partially observed system and provides it with autonomous management capabilities. We present the results of experimentation with cloud-based applications and discuss the technical challenges that need to be addressed in this field. Furthermore, we present the results of experimentation on a 5G network slice that hosts a cloud-based application in a multi-agent reinforcement learning setting, and demonstrate the value of information exchange between learning agents.

  • The controller placement problem for robust SDNs against malicious node
           attacks considering the control plane with and without split-brain
    • Abstract: In software-defined networking (SDN), the control plane is separated from the data plane. For scalability and robustness reasons, the logically centralized control plane is implemented by physically distributing different controllers throughout the network. The determination of the number and location of the SDN controllers is known as the controller placement problem (CPP). For given maximum switch-controller (SC) and controller-controller (CC) delays in the regular (failure-free) state, we aim to find a CPP solution that maximizes the control plane robustness against a given number of malicious node attacks. We describe an ILP-based method aiming to enumerate all CPP solutions that guarantee the existence of a data plane path from every switch to any controller if all other controller nodes are shut down (worst-case scenario). Then, for different malicious node attacks, based on node centrality metrics and corresponding to different attacker’s strategies, we evaluate the previous solutions to determine the ones that maximize the network robustness, considering the SDN control plane operating with or without split-brain. In the computational results, we compare the robustness and the average SC and CC delays of the best CPP solutions. Since a control plane with split-brain requires more controllers, the average SC and CC delays in the regular state of its CPP solutions are significantly better, on average. Concerning robustness, split-brain does not always provide the best robust CPP solutions due to its feature of requiring a minimum number of connected controllers (which must be over half of the total number of them) to be operational.

  • DAReSch: deadline-aware request scheduling for cloud storage services
    • Abstract: With the emergence of cloud computing and big data, many companies are increasingly relying on the cloud to store and retrieve tremendous amounts of data to leverage the scalability and performance offered by cloud storage services. As a result, data retrieval time has become of a paramount importance for cloud users especially. However, current data management systems are still not optimized to reduce such time. In this paper, we present a deadline-aware data request scheduling scheme, called DAReSch, that aims at scheduling data requests in order to minimize data transfer times and to meet the deadlines specified by the users. We show through real experiments using OpenStack storage system (i.e., Swift) that, compared with the traditional Swift Client system, DAReSch significantly increases the percentage of requests meeting their deadlines, reduces data transfer time, and maximizes bandwidth usage. Furthermore, we also study the impact of the request deadlines on the studied performance metrics. Our extensive experiments show that, when deadlines are stringent, DAReSh allows 60% of the requests to meet their deadline requirements compared with only 10% for the existing solution. When the deadline is less stringent, 90% of the requests can meet their deadline requirements with DAReSh compared with 40% for the existing solution.

  • 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.

  • A survey on authentication and access control for mobile networks: from 4G
           to 5G
    • Abstract: The next generation of mobile networks, 5G, is expected to support a set of multiple requirements and use cases that will create an improved user experience. 5G will also be able to provide a high level of security by considering a variety of security aspects, such as authentication and access control mechanisms. The current protocol in 4G designed to address security is 4G AKA. It presents some weaknesses and vulnerabilities that negatively affect operators’ networks and their subscribers’ security. In designing an authentication and access control mechanism for 5G, it is crucial to evaluate both 4G AKA’s weaknesses and the new requirements of 5G. In this paper, we survey the vulnerabilities of the 4G AKA protocol, as well as the current 5G architectural answers brought by the 3GPP.

  • Context-aware parallel handover optimization in heterogeneous wireless

    • Abstract: The key idea of this paper is to a use cross-layer triggering concept in order to control the vertical handover (VHO) in heterogeneous networks. Current mobility management protocols could not handle the ever-growing quality of service (QoS) demand for connected mobile nodes (MNs). Motivated by addressed challenging problems, the proposed multi-layer parallel handover optimization (MPHO) is capable of handling application awareness in its decision process. Each layer in the protocol stack implements its own decision mechanisms in response to environmental changes. Independent decisions may lead to un-optimal operation while reacting to the same event. MPHO coordinates triggered actions using a centralized controller. MPHO utilizes dynamic attributes to reduce HO latencies and signaling overheads with a more advanced coordination logic. It contains a prediction module that utilizes MN mobility patterns. Evaluation results validate the achieved enhancements with a smaller HO failure rate and increased throughput. MPHO achieves improvements in terms of perceived quality and delay constraints.

  • Embedded network design to support availability differentiation
    • Abstract: The problem of how to provide, in a cost-efficient manner, high levels of availability and service differentiation in communication networks was investigated in Tipper (Telecommun Syst 56(1): 5–16 2014), Gomes et al. (2014), and Alashaikh et al. (Comput Netw 82:4–19 2015). The strategy adopted was to embed in the physical layer topology a high availability set of links and nodes (termed the “spine”). The spine enables through protection, routing, and cross-layer mapping, the provisioning of differentiated classes of resilience with varying levels of end-to-end availability. Here, we present an optimization model formulation of the spine design problem, considering link availability and the cost of upgrading link availability. The design problem seeks to minimize the cost while attaining a desired target flow availability. Extensive numerical results illustrate the benefits of modifying the availability of a subset of links of the network to implement quality of resilience classes.

  • Low-latency and high-throughput software turbo decoders on multi-core
           architectures
    • Abstract: In the last few years, with the advent of a software-defined radio (SDR), the processor cores were stated to be an efficient solution to execute the physical layer components. Indeed, multi-core architectures provide both high-processing performance and flexibility, such that they are used in current base station systems instead of dedicated FPGA or ASIC devices. Currently, an extension of the SDR concept is running. Indeed, cloud platforms become attractive for the virtualization of radio access network functions. Actually, they improve the efficiency of the computational resource usage, and thus the global power efficiency. However, the implementation of a physical layer on a Cloud-RAN platform as discussed by Wubben and Paul (2016); Checko et al. (JAMA 17(1):405–426, 2015); Inc (2015); and Wubben et al. (JAMA 31(6):35–44, 2014) or FlexRAN platform as discussed by Wilson (2018); Foukas et al. (2017); Corp. (2017); Foukas et al. (2016) is a challenging task according to the drastic latency and throughput constraints as discussed by Yu et al. (2017) and Parvez (2018). Processing latencies from 10 μ s up to hundred of μ s are required for future digital communication systems. In this context, most of works about software implementations of ECC applications is based on massive frame parallelism to reach high throughput. Nonetheless, they produce unacceptable decoding latencies. In this paper, a new turbo decoder parallelization approach is proposed for x86 multi-core processors. It provides both: high-throughput and low-latency performances. In comparison with all CPU- and GPU-related works, the following results are observed: shorter processing latency, higher throughput, and lower energy consumption. Regarding to the best state-of-the-art x86 software implementations, 1.5 × to 2 × throughput improvements are reached, whereas a latency reduction of 50 × and an energy reduction of 2 × are observed.
