Mobile ad hoc networks: Energy-efficient real-time data communications

Abstract

A Mobile Ad Hoc Network (MANET) is an autonomous system of mobile nodes connected by wireless links to form a communication network. The challenge in the design of protocol architectures for MANETs is to provide a certain level of Quality of Service (QoS) in information transfer using the limited network resources, namely energy and bandwidth. This design goal is further constrained by the unreliable physical channel, the mobility of the nodes, and the lack of infrastructure for network coordination. To meet the QoS requirements for real-time data communication, some coordination of the channel is needed, but centralized coordination is not feasible in MANETs. Furthermore, since a MANET is a dynamic, distributed entity, the optimal control of such a system should also be dynamic and adaptive. 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, and an overview. © 2006 Springer. All rights reserved.
