This book presents the Time Reservation using Adaptive Control for Energy Efficiency (TRACE) family of protocol architectures that provide such dynamic coordinated channel access in a distributed manner enabling energy-efficient real-time data communications in MANETs. Furthermore this book provides an introduction to the fundamentals of MANETs an overview of protocols for each layer of the protocol stack and a discussion of the issues involved with energy-efficient protocol design and quality of service for real-time data transmission.
