Coverage analysis for target localization in camera sensor networks
Wireless Communications and Mobile Computing, 2011 ABSTRACTCamera sensor networks have recently emerged as a critical research topic. In this paper, we investigate the coverage problem for camera sensor networks. Specially, compared to the coverage problem for target detection which has been intensively studied, this paper studies the coverage problem from the perspective of target localization.
