Energy-Efficient Duty-Cycle Hybrid Medium Access Control Protocol for Wireless Sensor Network

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