摘要: 提出一种流量感知的信道访问控制协议TA-MAC.其核心思想是通过引入自适应机制来适应流量变化,根据负载的大小动态调整侦听期的实际长度,有效减小了空闲侦听.仿真结果表明, TA-MAC在满足保持丢包率为零,只轻微增加时延的情况下,显著降低了能耗.Abstract: This paper proposes a novel traffic-aware MAC mechanism,i.e.TA-MAC.The purpose is to be aware of flow changes and to limit the period of idle listening.Our simulation results show that TA-MAC reduces energy consumption significantly,compared to DW-MAC while keeping packet loss ratio to be zero and only increasing delivery latency slightly.
