Distance Based Deployment Approach to Improve the WSNs Coverage and Connectivity

Abstract

A "wireless sensor network (WSN)" represents the gathering of certain number of sensors that are closely deployed in a recognizable area. The efficiency of any WSNs is heavily depending on the coverage delivered by the deployed sensors. This paper suggested the development of "deployment approach" to improve the WSN coverage, connectivity and reliability. This approach is based on the "distance between" each sensor node and its neighboring sensors. It aims to improve the nodes coverage in steps after a primary arbitrary deployment. In each step, a sensor node is appealed in the direction of its neighbors that have lower distance. This reaction maximizes the coverage of the detected area by forcing the sensor to change its position towards the area with a lower sensors density. The simulation results were compared with the GSO results. Our results showed that this deployment approach could provide high coverage, full connectivity and good reliability. Such results could be achieved with less number of iterations.
