Cluster-based perimeter-coverage technique for heterogeneous wireless sensor networks

Sensor technologies have become vital today in gathering information about close by environments and its use in wireless sensor networks is getting widespread popular every day. Using heterogeneous nodes in a sensor network increases network reliability and lifetime. Our paper focuses on cluster head selection problem to improve full network coverage. Our proposed algorithm for cluster-based network organization is based on a perimeter-covered that support nodes deployed in densely populated network areas as better candidates for cluster head nodes. We provide performance metrics to analyze the performance of our approach and the simulation shows that the algorithm provides fairly accurate results.
