| 摘 要： | 针对无线传感器网络低能耗、低延时的特点,提出一种异步自适应MAC协议:AA-MAC.该协议缩短了无线传感器网络MAC协议中异步唤醒方式的前导帧长度,同时采用自适应监听来减少数据发送延时.通过在NS2上的仿真模拟比较,发现AA-MAC相对于同类型的MAC协议有更好的节能效果和更短的延时,因此AA-MAC能更适合无线传感器网络的要求.

| Abstract: | For the low power,low latency feature of wireless sensor networks(WSN),we provide a new asynchronous adaptive MAC protocol: AA-MAC.This MAC protocol shortens the preamble length of asynchronous arousal mode in MAC protocol in WSN,and uses adaptive sniffer to decrease the data sending delay.Simulating on NS2,we found the AA-MAC has better energy and latency efficiency than other similar MAC protocol,so AA-MAC fits the demand of WSN more. |
