Harmony Search based K Coverage Enhancement in Wireless Sensor Networks
Many wireless sensor network applications require K coverage of the monitored area. In this paper, we propose a scalable harmony search based algorithm in terms of execution time, K Coverage Enhancement Algorithm (KCEA) it attempts to enhance initial coverage, and achieve the required K coverage degree for a specific application efficiently. Simulation results show that the proposed algorithm achieves coverage improvement of 5.34% compared to K Coverage Rate Deployment (K CRD) which achieves 1.31% when deploying one additional sensor. Moreover, the proposed algorithm is more time efficient. Keywords Wireless Sensor Networks (WSN) Harmony Search
