Topology Control based on Demand MAC protocol for Wireless Sensor Networks

Abstract

In recent years, Wireless Sensor Networks (WSNs) have been applied in myriad of applications. As the sensor nodes are battery operated, the critical issue is to design WSNs with long life-time to fulfill their application requirements. Many energy conservation schemes have been proposed so far to increase the life-time of WSNs. In this paper, we explored the interactions between energy conservation protocols and introduced a novel hybrid protocol called Topology Control based On Demand MAC (TCODM) Algorithm that combines the benefits of Topology Control and Sleep Wake up schemes. It was found that by simultaneously applying multiple energy conservation schemes the average energy conservation increased by 68–82 % when compared to energy conservation protocols that are operated independently.
