摘要：One of the major issues in wireless sensor network (WSN) is how to cover the target field. In this paper, we consider the area coverage problem for irregular shaped target fields. The major deployment schemes are Random deployment scheme and Grid based deployment scheme. Random deployment is not suitable in all cases. In this strategy more than one sensor node may lie on the same place or region. And also no nodes may be there in some regions, so that the WSN uncovers the target field. Grid based deployment scheme will cover the target field more effectively than the random node deployment scheme. 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 field. 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.
