针对采用IEEE 802.15.4信标使能模式的分簇无线传感器网络，研究了简单的活动周期选择机制，提出了一种基于简单控制机制的自主分布式超帧持续时间(SD)选择机制，以减少信标冲突。该方案通过分布式监测信标接收功率，自主选择活动SD，并在传感器节点(SN)向其父簇头(CHS)引入信标状态通知，以避免CHS不必要的SD选择。计算机仿真结果表明，在集群移动环境下基于集群的无线传感器网络中，该方案在保持较好的功耗性能的同时，提高了TARS的任务性能。
This paper investigates simple active period selection mechanism for the cluster based WSNs employing traffic adaptive IEEE 802.15.4 beacon enabled mode, and proposes an autonomous distributed superframe duration (SD) selection scheme to reduce beacon collisions by using simple control mechanism. The proposed scheme autonomously selects an active SD by using beacon reception power monitoring with distributed fashion and also introduces a beacon status notice from sensor nodes (SNs) to their parent cluster heads (CHs) in order to prevent unnecessary SD selection at CHs. The results evaluated by computer simulation show that the proposed scheme can improve the tars mission performance while keeping the better power consumption performance in cluster-based WSNs under cluster mobility environments.
