Song Lingyang - Wireless device-to-device communications and networks

Covering the fundamental theory together with the state of the art in research and development, this practical guide provides the techniques needed to design, analyze, and optimize device-to-device (D2D) communications in wireless networking.

With an ever-increasing demand for higher-data-rate wireless access, D2D communication is set to become a key feature supported by next-generation cellular networks. This book introduces D2D-based wireless communications from the physical-, MAC-, network-, and application-layer perspectives, providing all the key background information before moving on to discuss real-world applications as well as potential future developments. Key topics are discussed in detail, such as dynamic resource sharing (e.g., of spectrum and power) between cellular and ad-hoc D2D communications to accommodate larger volumes of traffic and provide better service to users. Readers will understand the practical challenges of resource management, optimization, security, standardization, and network topology, and learn how the design principles are applied in practice.

Now that more and more new mobile multimedia-rich services are becoming available to mobile users, there is an ever-increasing demand for higher-data-rate wireless access. Therefore, new wireless technologies such as Long Term Evolution Advanced (LTE-A) and WiMAX have been introduced, which are capable of providing high-speed, large-capacity, and guaranteed-quality-of-service (QoS) mobile services. Apart from the new technologies, new techniques such as small-cell networks and heterogeneous networks (HetNets) have also been developed, which are able to improve network capacity by reducing cell size and effectively controlling the interference. However, all these attempts still rely on a centralized network topology, which entails mobile devices communicating with a base station or access point. Such a centralized network topology is inherently limited by the capabilities of the base station and access point, which could be congested due to the presence of a large number of communicating devices. Also, the base station and access point might not have complete information about transmission parameters among devices, which is required in order to achieve the optimal network performance. To mitigate this problem, the concept of device-to-device (D2D) communications has been introduced to allow local peer-to-peer transmission among mobile devices offloading traffic from the base station and access point. Also, it is crucial to increase the wireless network capacity to accommodate the bandwidth-consuming mobile applications and services. Device-to-device communications is a promising concept to improve user experience and resource utilization in cellular networks, operating in both licensed and unlicensed spectrum bands.
