Fault-Tolerant Wireless Sensor Networks

Abstract

In this chapter, we outline the current state of research for the design of fault tolerant wireless sensor networks. First, we discuss the various notions of faults as concerns a wireless sensor network, including fault characteristics, sources of faults, and random faults versus faults with particular temporal, geographical, or topology-related patterns. Second, we discuss techniques for fault prevention and management including techniques for detection and recovery. Finally, we provide a particular focus on a fault management in cluster-based wireless sensor networks, and outline current research directions in architecture design and recovery techniques, followed by the chapter summary.
