The lifetime of wireless sensor networks can be increased by minimizing the number of active nodes that provide complete coverage, while switching off the rest. In this paper, we ...
Abstract— With the rapid deployment of wireless sensor networks, there are several new sensing applications with specific requirements. Specifically, target tracking applicatio...
In this paper, we introduce a new type of coverage for wireless sensor networks, called Directed Coverage (DCoverage). Basically, D-Coverage is the coverage provided by a sensor n...
