本文旨在提供集群移动环境下的簇树型IEEE 802.15.4无线传感器网络的性能增强。簇的移动性导致严重的信标冲突，大大降低了系统的性能。为了提高系统性能的无线传感器网络与集群移动性，本文提出了一个简单的自主活动周期选择控制和流量自适应分布式退避机制的组合方案，在我们最近的工作中提出的，并调查了分布式退避系统性能的影响。计算机仿真结果表明，该方案可以提高簇树型无线传感器网络在簇移动环境下的传输性能和功率效率。
This paper aims to provide performance enhancement to cluster-tree type IEEE 802.15.4 WSNs under cluster mobility environments. The cluster mobility causes severe beacon collisions and greatly degrades the system performance. To enhance the system performance of WSNs with cluster mobility, the paper proposes a combination scheme of the simple autonomous active period selection control and the traffic adaptive distributed backoff mechanism, previously proposed in our recent work, and investigates an effect of the distributed backoff to the system performance. The results evaluated by computer simulation demonstrate the proposed scheme can improve the transmission performance and power efficiency in cluster-tree type WSNs under cluster mobility environments.
