Abstract

Wireless sensor networks (WSNs) are with sensor nodes that can sense certain physical characteristics and features to capture environmental information such as temperature, pressure, humidity sound, motion etc. WSNs are capable of forming a self-organizing network. A self organizing network is the one that gets up automatically without any form of manual setup or configuration. Again the deployment of these networks to cover the desired area in specific environment is a challenge. However, many works have been cited about this issue of area coverage problem with static sensor nodes but automatic configuration of sensor node with flexible mobility and less energy consumption are the matter of prime consideration. Again, suitable deployment schemes are crucial for achieving best link performance. This paper proposes a model based on artificial potential field along with rank of sensor node that decides which node will participate in mobility to cover the specified area. Our analytical study is based on Voronoi diagram and artificial potential fields which bring out significant outcomes.
