Energy efficient protocols for coverage maintenance in WSNs
Main Article Content
Abstract
Recent advances in wireless and sensing technologies enabled variety of applications in sensor networks. Some challenging issues have yet to be solved to achieve potentials of WSNs. Researchers focused much on energy conservation methods and little attention has been paid to coverage maintenance as quality of service (QOS) requirements. In this paper we have focused on improved heterogeneity aware clustering protocols and compare their performance on network life time and coverage maintenance under heterogeneity. Simulation results show the superiority of the proposed protocol for prolonging network life time and coverage maintenance.
