Wireless Sensor Networks (WSNs) are a rapidly growing area for research and commercial development. The sensor coverage problem is prime factor being considered in recent advances. The coverage concept is subject to a wide range of interpretations due to a variety of sensors and their applications. Different coverage formulations have been proposed in this paper. The Voronoi diagram for a sensor network is a diagram of boundaries around each sensor such that every point within a sensor's boundary is closer to that sensor than any other sensor in the network.
