Wireless Sensor Network (WSN) mainly composed of a number of sensor nodes whose prime responsibility is to sense various events from the surrounding, do the processing on top of it and finally propagate the meaningful information to the observer through multiple intermediate nodes. Area coverage is one of the issues in WSN that guarantees the selected active nodes among all the deployed nodes should...
In wireless sensor networks, to obtain a long network lifetime is a fundamental issue while without sacrificing crucial aspects of quality of service (area coverage, sensing reliability, and network connectivity). In this paper, we present a Voronoi-based sleeping configuration to deal with different sensing radii and location error. With our proposed sleeping candidate condition, redundant sensors...
