Abstract :

one of the major issues in a wireless sensor network (WSN) is how to cover an interested area. In this paper, we consider the area coverage problem for variable sensing radii WSN. There are various coverage techniques but we compare the cluster based coverage scheme, Grid based deployment scheme and Computational Geometry Based on the basis of idle nodes. In the cluster based system if the sensing range of the sensor node is less. The number of idle node is increase so that idle node cannot communicate with the cluster head and cannot cover the target area Grid based is the segregation of resources from multiple sites so as to solve a problem that can’t be solved by using the processing of a single computer. The basic Grid based deployment schemes are triangular, square and hexagon deployment schemes. But as the target field is not regular it is not possible to apply the grid based deployment schemes directly on the target. So, we proposed a method in which first the target field is divided into a collection of triangles using Delaunay Triangulation and then the triangular node deployment scheme is applied for each triangle. This presents an efficient coverage scheme for wireless sensor networks
