Success of Wireless Sensor Networks largely depends whether the deployed network can provide desired coverage with acceptable network lifetime. This paper proposes a distributed pr...
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...
