Constructing sensor barriers to detect intruders crossing restricted regions, such as country borders, is one of the major application categories for wireless sensor networks. In this paper, we present a distributed algorithm to find the maximum number of disjoint sensor barriers in wireless sensor networks. Our solution works for any sensor deployment, for any size and shape of a covered region,...
In this paper we propose GREASE, a distributed algorithm to deploy mobile sensors in an unknown environment with obstacles and field asperities that may cause sensing anisotropies and non uniform device capabilities. These aspects are not taken into account by traditional approaches to the problem of mobile sensor self-deployment. GREASE works by realizing a grid-shaped deployment throughout the Area...
