用于传感器网络周期性数据收集的自协商分时MAC协议
摘要
针对传感器网络周期性数据收集的数据流特点
提出了基于自协商时隙分配机制的自协商分时MAC协议。该时隙分配机制无需集中式处理
具有自适应、分布式、本地化等特点。仿真结果表明
本协议的有效数据收集率及最大数据延时与增添ACK重传机制后的TAG协议相当
而能耗却仅为后者的1/30。
Abstract
On the analysis of data flow characteristics in periodical data gathering applications in wireless sensor net- works
an auto-negotiation time division MAC protocol based on auto-negotiation slot allocation scheme was proposed. The slot allocation is carried out in the adaptive
distributed and localized manner. The simulation shows that power con- sumption in our protocol has been decreased to the one thirty of that in TAG protocol with extended ACK re-transmission scheme
while delivery ratio and maximum data latency suffer no deterioration.
