This SpringerBrief focuses on crucial issues for device-to-device (D2D) communications within the rapidly expanding 4G LTE toward 5G system. Several critical technical challenges in D2D communications are discussed, and D2D standardization activities in 3GPP are provided. Topics range from proximity discovery and mode selection, to resource management. The authors investigate proximity detection solutions for enabling direct user equipment communication by listening to uplink transmission. The problem of mixed mode selection is demonstrated to meet multiple quality of service (QoS) requirements in D2D enabled cellular networks. Finally, the brief explores the problem of designing interference-constrained resource allocation to pair cellular user resources with potential D2D links in cellular D2D underlay, with the goal of improving spectrum efficiency. Device-to-Device Communications in Cellular Networks targets researchers and professionals working in wireless communications and networks. Advanced-level students in electrical engineering and computer science studying wireless communications and networks can also use this material as a study guide.

In recent years, we have witnessed the emergence of mobile applications that attempt to introduce social awareness into mobile computing. These applications take advantage of person oriented contextual information (e.g., location, temporal, proximity, environment, etc.) to build innovative social services. A class of applications are to build social convenience, where a city service can collect individuals' context information from their mobile devices, and aggregate them for large-scale analytics (e.g., weather and urban mobility). Another class of applications are to create social connections, where an individual can employ his/her mobile device to monitor proximity and discover other individuals who share common interests. The goal of this dissertation is to facilitate the acceptance and participation of the above applications. A challenge for building social convenience is its applications, called public sourcing applications in this dissertation, compete with an individual's personal applications for the device's limited battery resource. As a result, neither the energy needs (and thus the quality) of sourcing applications nor the energy needs of personal applications can be assured. We define a novel framework sitting between individual volunteers and sourcing applications, which is used for managing energy resources on mobile devices as well as providing energy guarantees to sourcing applications. We use three key insights to build the framework. First, we can enable an individual to allocate energy into two smaller virtual batteries, one dedicatedly for the personal applications while the other one dedicatedly for the sourcing applications. Second, we can offer energy isolation to ensure that the personal applications own their virtual battery no matter how the sourcing applications use the device, and vice versa. Third, the aggregation of energy dedicated to sourcing applications on each device forms a pool of energy, and thus we can offer admission control service to sourcing applications and provide energy guarantee to those admitted sourcing applications. We further describe a generalized solution to the just-described energy isolation, where an individual may classify mobile applications according to his/her needs and have one virtual battery for each class. Each virtual battery has a semantic meaning to the individual, such as sourcing battery, entertaining battery or work-related battery, and thus he/she can interact with any specific virtual battery (i.e., reading its percentage level) to manage energy usages of the respective application class. To enable the energy isolation, we describe a novel energy accounting system that is not built on hardware-specific power models. The key insight is end users do not typically pay attention to energy activities of fine-grained software entities (e.g., thread or process) at second and/or millisecond levels. This allows an energy accounting approach to estimate energy usages by application classes at a fairly slow rate (e.g., at minute level). We thus employ an adaptive learning paradigm and use CPU time as the sole feature to estimate per-class energy consumption. As a result, the proposed approach offers two salient features: (i) Highly portable and immediately usable as it does not need to train hardware-specific power models, and (ii) Self adaptive as it sequentially remodels per-class energy consumption in response to varying hardware, system and application states. For building social connections, we focus on "familiar stranger" social relations in which strangers are repetitively collocated with each other. This type of relation was first observed in 1972 by Stanley Milgram, followed by an increasing number of social network research. With mobile devices that monitor proximity context, discovering familiar strangers becomes easier. In this dissertation, we enable commuters traveling on public buses or trains to enjoy multiplayer gaming with their fellow commuters, called public gaming. We define a discovery/matchmaking framework which help people discover familiar peer players on the same train/bus. We perform extensive measurement and evaluation to interpret the possibility of offering public gaming, and design an end-to-end system that provides guarantee to high-quality group experience. At the cloud side, a matchmaking service guides neighbor discovery and group formation. Once a group is formed and the group leader is selected, mobile side gaming would be built on p2p communication techniques such as Bluetooth and Wi-Fi Direct. Finally, we invite people to use the system in crowded transport settings and play latency-sensitive games (e.g., First-Person Shooter).

The objective of this SpringerBrief is to present security architectures and incentive mechanisms to realize system availability for D2D communications. D2D communications enable devices to communicate directly, improving resource utilization, enhancing user’s throughput, extending battery lifetime, etc. However, due to the open nature of D2D communications, there are two substantial technical challenges when applied to large-scale applications, that is, security and availability which is demonstrated in this book. This SpringerBrief proposes a secure data sharing protocol, which merges the advantages of public key cryptography and symmetric encryption, to achieve data security in D2D communications. Furthermore, a joint framework involving both the physical and application layer security technologies is proposed for multimedia service over D2D communications thus the scalable security service can be achieved without changing the current communication framework. Additionally, as the system availability largely depends on the cooperation degree of the users, a graph-theory based cooperative content dissemination scheme is proposed to achieve maximal Quality of Experience (QoE) with fairness and efficiency. This SpringerBrief will be a valuable resource for advanced-level students and researchers who want to learn more about cellular networks.

Green communications is a very hot topic. As mobile networks evolve in terms of higher rates/throughput, a consequent impact on operating costs is due to (aggregate) network energy consumption. As such, design on 4G networks and beyond have increasingly started to focus on `energy efficiency’ or so-called ‘green’ networks. Many techniques and solutions have been proposed to enhance the energy efficiency of mobile networks, yet no book has provided an in-depth analysis of the energy consumption issues in mobile networks nor has detailed theories, tools and solutions for solving the energy efficiency problems. This book presents the techniques and solutions for enhancing energy efficiency of future mobile networks, and consists of three major parts. The first part presents a general description of mobile network evolution in terms of both capacity and energy efficiency. The second part discusses the advanced techniques to green mobile networks. The third part discusses the solutions that enhance mobile network energy efficiency as well as provides future directions. Whilst the reader is expected to have basic knowledge of wireless communications, the authors present a brief introduction of the evolution of mobile networks, providing the knowledge base for understanding the content of the book. In addition, complicated network problems are illustrated using simple examples. This will help the reader understand the concept and intuition of various techniques and solutions. Incorporates the latest research results from both academia and industry, providing an up-to-date overview of existing technologies and solutions on making mobile networks greener Consists of three sections with a gradually increasing technical depth on green mobile networks, providing the reader with a systematic view of the research area, and helping those with different technical backgrounds to better understand the content Covers existing enabling technologies for green mobile networking, including an innovative discussion of state-of-the-art solutions and algorithms
