This book presents the Time Reservation using Adaptive Control for Energy Efficiency (TRACE) family of prool 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 prools for each layer of the prool stack, and a discussion of the issues involved with energy-efficient prool design and quality of service for real-time data transmission.
