Connected Target Coverage for Fully Data Gathering in Wireless Sensor Networks

Coverage problem is an important issue in wireless sensor networks, which has a great impact on the performance of wireless sensor networks. Many researches in this area only focus on how to cover all the targets in the network, which ignore considering the problem of how to transmit the sensing data to the sink. In this paper, we propose an energy-effective connected target coverage algorithm named ECTCG to guarantee the sensed data be effectively gathered in mobile wireless sensor networks. We theoretically analyze ECTCG algorithm and conduct extensive simulations to evaluate its performance. Simulation results show that ECTCG outperforms another existing algorithm CWGC by effectively prolonging the network lifetime. Copyright © 2013 IFSA.
