基于同步调度的低占空比无线传感器网络MAC协议
摘要
SCP-MAC协议相邻节点间的同步唤醒
如果通信负荷增加
会产生较高的无意侦听
会降低能效和吞吐量
造成拥塞。提出了一种基于同步调度的超低占空比MAC协议ESCP-MAC
优化了唤醒调度方式
减少相邻节点的竞争
采用低功耗侦听的方式同步。仿真和实验结果表明:提出的协议在继承SCPMAC协议低能耗优势的基础上
改善了多跳传输的端到端延时性能
减少了丢包率。
Abstract
In SCP-MAC protocol
synchronous awakening between adjacent nodes
with the increase of communication load
will cause unintentional listening and decline of energy efficiency and handling capacity
which can lead to network congestion. A low-duty-ratio MAC protocol is proposed. It optimizes the awakening scheduling mode
reduces the competition of adjacent nodes and synchronizes with low-power consumption listening. The simulation results shows that ESCP-MAC protocol retains the advantage of low energy consumption
improves characteristics of end-to-end delay and reduces rate of packet loss.
