Abstract

This paper proposes an energy-efficient hybrid medium access control protocol based on precise control of duty cycle. To save energy, the proposed protocol optimally adjusts the trans-receiver radio's turn-on and off time. By estimating slot utilization, both the cluster head and the sensing devices save energy. During the reserved slot duration, each sensor device periodically checks its buffer status and turns off its radio when the buffer becomes empty. Each sensor device sends a slot utilisation status to the cluster head device. The cluster head device also turns its radio on and off based on the slot utilisation status of sensing devices. For optimal energy consumption, a duty cycle approach is proposed. According to the mathematical and simulation results, the proposed protocol consumes less energy than existing equivalent protocols. Simulation results depict, exactly similar results of analytical and mathematical analysis prove the validity of the work.
