摘要

新的IEEE 802.15.4标准支持低速率、低功耗个人区域网络的部署。它提供了一种在运行时适应协议占空比的机制。在ieee802.15.4星型拓扑网络中，提出了一种新的信标顺序自适应算法BOAA。在这种网络中，协调器通过观察通信频率来确定所需的占空比，并相应地调整信标间隔。研究表明，该算法可以根据消息延迟进行权衡，从而实现节能

A new beacon order adaptation algorithm for IEEE 802.15.4 networks

The new IEEE 802.15.4 standard enables deployment of low-rate low-power personal area networks. It provides a mechanism for adaptation of the protocols duty cycle during runtime. In this paper we propose BOAA, a new algorithm for beacon order adaptation in IEEE 802.15.4 star-topology networks. By observing the communication frequency, the coordinator in such a network determines the required duty cycle and adapts the beacon interval accordingly. Investigations reveal that the algorithm enables power saving with a trade-off according to message delay
