无线传感器网络（WSNs）非常适合于许多应用，包括环境监测和目标跟踪。ZigBee是一种基于IEEE 802.15.4的标准，被认为适用于无线传感器网络。ZigBee网络的功能运行依赖于自组织网络连接和传感器设备的正确部署。然而，由于ZigBee标准的配置约束，包括ZigBee网络的设备在加入阶段之后可能变得与网络隔离。这意味着一些部署的设备无法加入网络，即使它们可以与其他加入的节点通信。这些孤立的设备降低了网络运行效率，增加了部署成本。本文提出了一种ZigBee兼容的自适应加入机制，连接转移方案，以提高ZigBee网络的连通性，使它们能够以预期的效率运行。仿真结果表明，该机制显著提高了ZigBee无线传感器网络中传感器设备的加入率。版权所有© 2009约翰威利父子有限公司。
Wireless sensor networks (WSNs) are well suited to many applications, including environment surveillance and target tracking. ZigBee is an IEEE 802.15.4‐based standard that is considered suitable for WSNs. The functional operations of a ZigBee network rely on self‐organized network connections and the proper deployment of sensor devices. However, the devices comprising a ZigBee network may become isolated from the network after the joining phase due to the configuration constraints of the ZigBee standard. This means that some deployed devices cannot join the network even though they can communicate with other joined nodes. These isolated devices reduce the efficiency of network operation and increase deployment costs. This paper proposes a ZigBee‐compatible adaptive joining mechanism with connection shifting schemes to improve the connectivity of ZigBee networks, allowing them to operate at the expected efficiency. Simulation results show that the proposed mechanism significantly improves the join ratio of deployed sensor devices in ZigBee WSNs. Copyright © 2009 John Wiley & Sons, Ltd.
