基于ieee802.15.4的动态自适应占空比方案
Keywords: ieee802.15.4,业务流量,占空比,能量消耗
Abstract:
在无线传感器网络中,ieee802.15.4协议采用固定的占空比机制,而网络流量却是动态变化的,所以固定的占空比机制不适合于动态的网络流量.因此,本文提出了一种动态自适应占空比方案dsba(dynamicsuperframeorderbeaconorderadaption),该方案通过感知网络流量动态调整节点占空比,即对比当前节点所能处理的数据帧数量和下一周期将要收到的数据帧数量,动态调整占空比使之适合网络流量传输从而提高网络性能.仿真结果表明该方案不仅减少了能量消耗,也降低了丢包率和传输延迟.
