Abstract: Barrier coverage is an important issue in wireless sensor networks, which guarantees to detect any intruder attempting to cross a barrier or penetrating a protected region monitored by sensors. However, the barrier coverage problem in wireless camera sensor networks (WCSNs) is different from that in scalar sensor networks. In this paper, based on (k, ω)-angle coverage, we study the minimum (k, ω)-angle barrier coverage problem in WCSNs. We first present the technique to deploy minimum number of camera sensors to form a (k, ω)-angle barrier. Then propose a novel method to select the minimum number of camera sensors from an arbitrary deployment to form a (k, ω)-angle barrier. Though our simulation, we confirm that our algorithms reduce the number of sensors required comparing to the state-of-art algorithm.
