This topic is explored with various key challenges in diverse scenarios, including architecture, capacity, connectivity, scalability, medium access control, scheduling, dynamic channel assignment and cross-layer optimization. The main focus of this book is the introduction of concepts, effective protocols, system integration, performance analysis techniques, simulations and experiments, and more importantly, the direction of future research in the watershed. The first part of this book introduces DAS fundamentals, including channel models and theoretical issues, examining the capacity of DAS with different structures. Concentrating on the MAC and protocols for the DAS, the second part of this book includes information on distributed signal processing, optimal resource allocation, cooperative MAC protocols, cross layer design, and distributed organization.
