摘要: Recently low power listening (LPL) MAC protocols based on duty-cycling mechanism have been studied extensively to achieve ultra energy consumption in wireless sensor networks (WSNs). However, state-of-the-art LPL scheme still suffers from some performance degradation due its own protocol incompleteness. In this paper, we propose the τ-duration CCA method mitigate collision probability ACK-based and show improvement via analytical experimental results. Our study indicates that which adopts is significantly better than normal terms of consumption.
