摘要
为了研究移动节点存在下的Zigbee无线传感器网络性能,建立基于OPNET模拟器的Zigbee仿真模型,对移动节点存在下ZigBee网络MAC负载、数据丢包率、树状网络跳数、网络层泛关系和应用层流量的仿真进行研究。仿真结果表明,网络中节点的移动会引起网络结构的变化,Zigbee网络的自组织能力、数据丢包时空域和有效应用层流量对整个网络性能产生了明显的影响。
To study the performance of Zigbee wireless sensor networks with mobile nodes, a simulation model of Zigbee is established by using the OPNET simulator. A simulation study is carried out on Zigbee MAC load per PAN, data packet loss rate, tree network hops, PAN affiliation, and application traffic received in the presence of mobile Zigbee node. The results of simulation indicate that the mobility of nodes in the network will bring changes in network structure ; self-organizing ability, data packet loss in temporal-spatial domain and effective application traffic received all have a significant impact on the performance of the network.
