Towards an Energy-Efficient Algorithm Based Sleep-Scheduling for Wireless Sensor Networks

Abstract

In this paper, we investigated the issue of energy conservation, in the WSNs, by keeping a minimum number of sensor nodes to operate in active mode as well as ensure network connectivity. To address this problem, we proposed a Geographical Topology Control (GTC) Protocol to reduce energy consumption in wireless sensor network by sleep scheduling among sensor nodes. The simulation results of GTC show that it can consume 30% less energy than GAF protocol. Moreover, GTC extends the network lifetime by 20% compared to GAF.
