Sensor nodes have limited lifetime batteries due to high energy consumption. Energy conservation and coverage are two major problems in Wireless Sensor Networks. The objective of this paper is to minimize the energy consumption while maintaining the full sensing coverage and extend the network lifetime. The main focus of this paper is to obtain increase the network lifetime, minimize the energy consumption, as well as maintain the full coverage. In this paper, the authors propose a ERGS (Energy Remaining Greedy Scheduling algorithm), which can reduce overall energy consumption, therefore increasing network lifetime, by minimize the number of active nodes. They implement their proposed scheme in NS-2 as an extension of Energy Remaining Greedy Scheduling Algorithm.
