  • Age of Information: A New Concept, Metric, and Tool
    • Abstract: Age of information (AoI) was introduced in the early 2010sas a notion to characterize the freshness of the knowledgea system has about a process observed remotely. AoI wasshown to be a fundamentally novel metric of timeliness,significantly different, to existing ones such as delay andlatency. The importance of such a tool is paramount, especiallyin contexts other than transport of information, sincecommunication takes place also to control, or to compute,or to infer, and not just to reproduce messages of a source.This volume comes to present and discuss the first body ofworks on AoI and discuss future directions that could yieldmore challenging and interesting research.Suggested CitationAntzela Kosta, Nikolaos Pappas and Vangelis Angelakis (2017), "Age of Information: A New Concept, Metric, and Tool", Foundations and Trends® in Networking: Vol. 12: No. 3, pp 162-259. http://dx.doi.org/10.1561/1300000060

  • Network and Protocol Architectures for Future Satellite Systems
    • Abstract: Since their conception, satellite communications have been regarded as apromising tool for all environments where the terrestrial infrastructure islimited in capacity or to take advantage of the multicasting/broadcastingcapabilities inherent in satellite technology. Recent advances have seen satellitetechnology mature to a more prominent role in the telecommunicationsdomain. In particular, the design of novel satellite payload concepts for Geostationary(GEO) satellite platforms, as well as renewed interest in Low EarthOrbit (LEO) satellite constellations have made the integration of satellite andterrestrial networks almost compulsory to ensure new services meet the requirementsfor high user-rate and quality of experience that could not beachieved using either of the two technologies independently. From this viewpoint,convergence of satellite and terrestrial technologies also requires consideringthe most recent trends in networking, with special attention beingpaid to the potential new architectures that have been recently proposed inthe framework of Future Internet.This monograph explores the main components of the scenarios above,putting particular emphasis on the networking aspects. To this end, novelprotocols such as Multi Path TCP (MPTCP) and networking trends such asInformation Centric Networking (ICN) are explored by demonstrating theirapplicability in some scenarios that deploy both satellite and terrestrial segments.Particular attention is given to smart gateway diversity schemes whichadvocate the use of sophisticated multi-path transmission schemes to exploitthe multi-homing features offered by present day devices. The second part ofthe monograph is dedicated to content-based networking, which is becomingincreasingly popular driven by the pervasiveness of the Internet in everydaylife. In this regard, applications to satellite communications are illustratedand the technical challenges to be further addressed are highlighted.Suggested CitationTomaso de Cola, Alberto Ginesi, Giovanni Giambene, George C.

  • Duality of the Max-Plus and Min-Plus Network Calculus
    • Abstract: The network calculus is a framework for the analysis of communication networks,which exploits that many computer network models become tractablefor analysis if they are expressed in a min-plus or max-plus algebra. In amin-plus algebra, the network calculus characterizes amounts of traffic andavailable service as functions of time. In a max-plus algebra, the network calculusworks with functions that express the arrival and departure times or therequired service time for a given amount of traffic. While the min-plus networkcalculus is more convenient for capacity provisioning in a network, themax-plus network calculus is more compatible with traffic control algorithmsthat involve the computation of timestamps. Many similarities and relationshipsbetween the two versions of the network calculus are known, yet theyare largely viewed as distinct analytical approaches with different capabilitiesand limitations. We show that there exists a one-to-one correspondencebetween the min-plus and max-plus network calculus, as long as traffic andservice are described by functions with real-valued domains and ranges. Consequently,results from one version of the network calculus can be readilyapplied for computations in the other version. The ability to switch betweenmin-plus and max-plus analysis without any loss of accuracy provides additionalflexibility for characterizing and analyzing traffic control algorithms.This flexibility is exploited for gaining new insights into link scheduling algorithmsthat offer rate and delay guarantees to traffic flows.Suggested CitationJörg Liebeherr (2017), "Duality of the Max-Plus and Min-Plus Network Calculus", Foundations and Trends® in Networking: Vol. 11: No. 3-4, pp 139-282. http://dx.doi.org/10.1561/1300000059

  • Modern Random Access Protocols
    • Abstract: Random access represents possibly the simplest and yet one of the best known approaches for sharing a channel among several users. Since their introduction in the 1970s, random access schemes have been thoroughly studied and small variations of the pioneering Aloha protocol have since then become a key component of many communications standards, ranging from satellite networks to ad hoc and cellular scenarios. A fundamental step forward for this old paradigm has been witnessed in the past few years, with the development of new solutions, mainly based on the principles of successive interference cancellation, which made it possible to embrace constructively collisions among packets rather enduring them as a waste of resources. These new lines of research have rendered the performance of modern random access protocols competitive to that of their coordinated counterparts, paving the road for a multitude of new applications.This monograph explores the main ideas and design principles that are behind some of such novel schemes, and aims at offering to the reader an introduction to the analytical tools that can be used to model their performance. After reviewing some relevant results for the random access channel, the volume focuses on slotted solutions that combine the approach of diversity Aloha with successive interference cancellation, and discusses their optimisation based on an analogy with the theory of codes on graphs. The potential of modern random access is then further explored considering two families of schemes: the former based on physical layer network coding to resolve collisions among users, and the latter leaning on the concept of receiver diversity. Finally, the opportunities and the challenges encountered by random access solutions recently devised to operate in asynchronous, i.e., unslotted, scenarios are reviewed and discussedSuggested CitationMatteo Berioli, Giuseppe Cocco, Gianluigi Liva and Andrea Munari (2016), "Modern Random Access Protocols", Foundations and Trends® in Networking: Vol. 10: No. 4, pp 317-446. http://dx.doi.org/10.1561/1300000047

  • Opportunistic Routing in Wireless Networks
    • Abstract: Wireless multi-hop networks have become an important part of many modern communication systems. Opportunistic routing aims to overcome the deficiencies of conventional routing on wireless multi-hop networks, by specifically utilizing wireless broadcast opportunities and receiver diversity. Opportunistic routing algorithms, which are specifically optimized to incorporate into the routing decisions a model of wireless transmission, take advantage of scheduling, multi-user, andreceiver diversity gains and result in significant reduction in the expected cost of routing per packet. The ability of the algorithm to take advantage of the aspects of wireless transmission, however, depends on the scalability and the additional overhead associated with the opportunistic routing as well as the availability of side information regarding wireless channel statistics, topology, etc. This monograph sheds light on the performance gains associated with incorporating into the routing strategy the nature of wireless transmission.This monograph first provides an overview of various opportunistic distance-vector algorithms that have been developed to incorporate wireless transmission and routing opportunities. Furthermore, an optimal opportunistic distance metric is proposed whose performance is examined against the performance of several routing algorithms from the literature. The performance is examined first in analytical examples, then via simulation to identify the strengths of the optimal opportunist routing algorithm. To allow for a scalable and distributed solution, the distributed computation of this optimal distance-metric is provided. The performance of a distributed implementation of the optimal opportunistic routing algorithm is also examined via simulation. In addition to the construction of the opportunistic schemes in centralized and distributed fashions, this monograph also addresses how learning the wireless medium can be efficiently incorporated in the structure of routing algorithm. Finally, this monograph examines the dynamic congestion-based distance metric and its performance against other congestion aware solutions in the literature.Suggested CitationTara Javidi and Eric Van Buhler (2016), "Opportunistic Routing in Wireless Networks", Foundations and Trends® in Networking: Vol. 10: No. 4. http://dx.doi.org/10.1561/1300000021

  • Modeling and Optimization of the Smart Grid Ecosystem
    • Abstract: The smart energy grid has evolved into a complex ecosystem, with new entering actors such as aggregators, and traditional ones like consumers, operators and generators having fundamentally different, active roles in the system. In addition, advances in key technologies such as renewables, energy storage, communication and control have paved the way to new research directions and problems. In this work we attempt to give some structure to the complex ecosystem above, and we present key research problems that shape the area. The emphasis is on the control and optimization methodology toward approaching these problems. The first thread we consider is demand-response where the central theme is to optimize the demand load of consumers. The basic problem is the scheduling of demand load of consumers with the aim to minimize a cost function from the point of view of the utility operator or the consumer. Next, we review fundamental problems in energy storage management. The basic energy storage management problem amounts to deciding when and how much to charge and discharge the battery in order to achieve a certain optimization objective, either in terms of a generation cost or a mismatch between energy demand and supply, which again may capture the goals of the consumer or the utility. We also discuss the market interactions of various entities in the smart grid ecosystem and the impact of their strategic decisions on the market structure. Finally, we study key aspects of consumer behavior such as response to gamification models, and uncertainty due to consumer decisions that influence the system, and we discuss the role of data in building data-driven models for predicting consumer behavior. For each problem instance above, we provide an exposition that places emphasis on the related model and on key aspects of the analysis.Suggested CitationIordanis Koutsopoulos, Thanasis G.

  • Millimeter Wave Vehicular Communications: A Survey
    • Abstract: Future vehicles will require massive sensing capability. Leveraging only onboard sensors, though, is challenging in crowded environments where the sensing field-of-view is obstructed. One potential solution is to share sensor data among the vehicles and infrastructure. This has the benefits of providing vehicles with an enhanced field-of-view and also additional redundancy to provide more reliability in the sensor data. A main challenge in sharing sensor data is providing the high data rates required to exchange raw sensor data. The large spectral channels at millimeter wave (mmWave) frequencies provide a means of achieving much higher data rates. This monograph provides an overview of mmWave vehicular communication with an emphasis on results on channel measurements, the physical (PHY) layer, and the medium access control (MAC) layer. The main objective is to summarize key findings in each area, with special attention paid to identifying important topics of future research. In addition to surveying existing work, some new simulation results are also presented to give insights on the effect of directionality and blockage, which are the two distinguishing features of mmWave vehicular channels. A main conclusion of this monograph is that given the renewed interest in high rate vehicle connectivity, many challenges remain in the design of a mmWave vehicular network.Suggested CitationVutha Va, Takayuki Shimizu, Gaurav Bansal and Robert W.

  • Building Reliable Storage Clouds: Models, Fundamental Tradeoffs, and
           Solutions
    • Abstract: Distributed storage has been an active research area for decades. With the proliferation of cloud computing, there has been a rejuvenated interest in two perspectives. The first perspective is seen through the lenses of the cloud providers: how should we build global storage services for cloud hosted services and applications at scale with high reliability and availability guarantees, but also in a cost effective way' The second perspective is seen through the lenses of the service providers that utilize public clouds: how can we achieve high I/O performance over cloud storage within a cost budget' In this manuscript, we first present various kinds of distributed storage systems, their operational characteristics and the key techniques to improve their performance. We then focus on cloud storage, exclusively. Cloud storage has massive scales with the promise to provide as much storage capacity as their tenants demand. Cloud providers also promise very high durability, availability, and I/O performance. In this context, we cover the fundamental tradeoffs between storage efficiency and network bandwidth as well as I/O throughput and latency. Erasure codes play an essential role in these tradeoffs and, thus, we also present their design and usage in the context of cloud storage broadly. We pay particular attention on various queuing models and the corresponding performance analysis in the presence of coded storage. We provide exact and approximate solutions under various settings and assumptions. We describe optimal or near-optimal scheduling and coding strategies that are established based on these analyses.Suggested CitationUlas C.

  • Wireless Network Optimization by Perron-Frobenius Theory
    • Abstract: A basic question in wireless networking is how to optimize the wireless network resource allocation for utility maximization and interference management. How can we overcome interference to efficiently optimize fair wireless resource allocation, under various stochastic constraints on quality of service demands' Network designs are traditionally divided into layers. How does fairness permeate through layers' Can physical layer innovation be jointly optimized with network layer routing control' How should large complex wireless networks be analyzed and designed with clearly-defined fairness using beamforming' This monograph provides a comprehensive survey of the models, algorithms, analysis, and methodologies using a Perron-Frobenius theoretic framework to solve wireless utility maximization problems. This approach overcomes the notorious non-convexity barriers in these problems, and the optimal value and solution of the optimization problems can be analytically characterized by the spectral property of matrices induced by nonlinear positive mappings. It also provides a systematic way to derive distributed and fast-convergent algorithms and to evaluate the fairness of resource allocation. This approach can even solve several previously open problems in the wireless networking literature. More generally, this approach links fundamental results in nonnegative matrix theory and (linear and nonlinear) Perron-Frobenius theory with the solvability of non-convex problems. In particular, for seemingly nonconvex problems, e.g., max-min wireless fairness problems, it can solve them optimally; for truly nonconvex problems, e.g., sum rate maximization, it can even be used to identify polynomial-time solvable special cases or to enable convex relaxation for global optimization.To highlight the key aspects, we also list several case studies of using the nonlinear Perron-Frobenius theoretic framework for applications in MIMO wireless cellular, heterogeneous small-cell and cognitive radio networks. Key implications arising from these work along with severalopen issues are discussed in this monograph.Suggested CitationChee Wei Tan (2015), "Wireless Network Optimization by Perron-Frobenius Theory", Foundations and Trends® in Networking: Vol. 9: No. 2-3, pp 107-218. http://dx.doi.org/10.1561/1300000048

  • A Clean Slate Approach to Secure Wireless Networking
    • Abstract: The current process of designing secure protocols is tantamount to an arms race between attacks and “patches”. We introduce a system theoretic approach to secure protocol design with provable security guarantees against all attacks that fall within the system model. In this approach, we frame the secure protocol design problem as a max-min optimization of a specific payoff function, where the adversarial nodes with a priori knowledge of the protocol choose a strategy that minimizes the payoff, and the protocol seeks to maximize this worst-case payoff. We make the following three contributions. First, we solve the optimization problem. That is, we describe a protocol and show that is max-min optimal. Second, we show that the protocol is actually min-max optimal which is generally higher than max-min optimality. Finally, we show that the adversarial nodes are effectively limited to one of two modes: either jamming or conforming with the protocol.Suggested CitationJonathan Ponniah, Yih-Chun Hu and P. R.

  • Online Learning Methods for Networking
    • Abstract: In this monograph we provided a tutorial on a family of sequential learning and decision problems known as the multi-armed bandit problems. We introduced a wide range of application scenarios for this learning framework, as well as its many different variants. The more detailed discussion has focused more on the stochastic bandit problems, with rewards driven by either an IID or a Markovian process, and when the environment consists of a single or multiple simultaneous users. We also presented literature on learning of MDPs, which captures coupling among the evolution of different options that a classical MAB problem does not.Suggested CitationCem Tekin and Mingyan Liu (2015), "Online Learning Methods for Networking", Foundations and Trends® in Networking: Vol. 8: No. 4, pp 281-409. http://dx.doi.org/10.1561/1300000050
