Resource Management for Heterogeneous Wireless Networks

This book provides a comprehensive and in-depth discussion on how resources of heterogeneous wireless networks can be managed to optimize the network capacity. Then it presents the techniques that can be incorporated within heterogeneous wireless networks to increase the efficiency of resource utilization, such as interworking of the networks, multi-homing and device-to-device (D2D) communication, and their advantages are discussed. It also introduces an overview of how and where each of these techniques can be applied. This book also focuses on three key areas of a typical heterogeneous wireless network, and provides detailed discussions on how network resources can be managed in each area to maximize the network capacity. The three areas are: 1) an area with interworking cellular networks and wireless local area networks (WLANs); 2) an area with interworking and D2D communication underlaying cellular networks and WLANs; and 3) an area with interworking macrocell and hyper-dense small cell networks. For each of these areas, a comprehensive literature review on the existing resource allocations schemes is provided. The challenges to allocate resources and the potential solutions are also discussed. Then, the proposed state of the art optimal and heuristic resource allocation schemes, which overcome those challenges to allocate resources are described. The proposed schemes have been designed to be able to deploy in real networks, hence they utilizes cloud computing to determine the resource allocation decisions and operates on multiple timescales to satisfy characteristics of different networks. This book concludes with a discussion on the future research directions on the related fields of study. Advanced-level students focused on communication and networking will use this book as a study guide. Researchers and experts in the fields of networking, converged networks, small-cell networks, resource management, and interference management, as well as consultants working in network planning and optimization and managers, executives and network architects working in the networking industry will also find this book useful as a reference.
