Determination and Patching of Coverage Holes in Hybrid WSN with Energy Aware Routing

Abstract

In the recent days, wireless sensor network that consists of several tiny sensors has been extensively used. One of the predominant demanding situations in such networks is a way to cover the sensing region effectively and maintain longer network lifetime with restricted power simultaneously. In this system, a hybrid sensor network, which contains both static and mobile sensors under random distribution, is being observed. Here the monitoring plane is divided into triangles using Delaunay Triangulation algorithm, in order to estimate coverage holes produced by static sensors. Mobile nodes are deployed to provide assistance in case of hole formation. Subsequently, nearest mobile sensors will move to heal the coverage holes.[8]In comparison with the similar strategies, the system proposed here is less complicated, and the major highlights of the system are that it facilitates a relatively simple effort to estimate the coverage holes, deployment of assisted mobile sensors to provide a better communication experience, connectivity to sink made in energy efficient manner to provide prolonged network lifetime thereby maintaining the overall quality of the network.
