This book provides the state-of-the-art research on aerial communications coexisting with terrestrial networks from physical, MAC, network, and application layer perspectives. It includes thorough discussion of control issues, access techniques and resource sharing between cellular communication and aerial communications to accommodate larger volumes of traffic and to provide better service to users. Other challenges are explored in this text are: identification of services, radio resource allocation and resource management for aerial links, self-organizing aerial networks, aerial offloading, and performance evaluation of aerial communications. This volume will be a highly useful resource for students, researchers and engineers interested in obtaining comprehensive information on the design, evaluation, and applications of aerial access networks and communications.
