一种动态占空比的无线传感器网络MAC协议
Medium Access Control Protocol with Dynamic Duty Cycle in Wireless Sensor Network
摘要
Abstract
Lowering the energy consumption may result in higher latency Wireless Sensor Network(WSN). To address such a tradeoff, this paper proposes a Media Access Control(MAC) protocol based on dynamic duty cycle. It adjusts duty cycle dynamically based on utilization, average sleeping delay, and the upper and lower bound of duty cycle. Experimental results show that the MAC protocol saves energy about 52% and reduces latency by 35% from S-MAC in a chain topology. In the cross topology, it achieves 68% energy saving and 46% latency reduction from S-MAC.关键词
