Sensor coverage in wireless sensor networks

Abstract

Coverage problem is an important and fundamental issue in sensor networks, which reflects how well a sensor network is monitored or tracked by sensor. In this chapter, we survey the current works on coverage problem in sensor networks. Two types of sensor coverage are investigated: area coverage and target coverage. Combining with sensor development mechanism (deterministic, statistical) and wireless sensor network properties (e.g. network connectivity, energy efficient and fault tolerant for connectivity and sensing etc), various coverage problems have been introduced and discussed in details. We focus on the most representative problems in each domain and present a comprehensive review and analysis of various existed algorithms, techniques. © 2009 Nova Science Publishers, Inc.
