OPNET作为一种网络模拟器已经得到了广泛的应用，但是在ZigBee无线传感器网络（WSN）中，这种模拟器的性能并没有得到太多的重视。由于硬件设计、能量限制和大量节点的部署，无线传感器网络的仿真是一项具有挑战性的任务。本文在OPNET模拟器中对不同WSN拓扑和路由方案下ZigBee协议的QoS性能评估进行了全面的研究和分析。通过对仿真结果的分析，本文可以作为研究人员评估OPNET Modeler作为Zigbee网络WSN模拟器的指南。讨论了OPNET Modeler中需要进行的一些改进，使其更适合ZigBee无线传感器网络的仿真。
OPNET has been widely used as a network simulator, but not much emphasis has been given on the performance of this simulator for ZigBee wireless sensor networks (WSN). Simulation of WSNs is a challenging task due to the nature of hardware design, energy limitations, and deployment of a vast number of nodes. An inclusive study and analysis of the QoS performance evaluation of the ZigBee protocol within the OPNET simulator for different WSN topologies and routing schemes is presented here. Based on simulation and analysis of results this paper can be considered as a guide for researchers in evaluating OPNET Modeler as a WSN simulator for Zigbee networks. Some enhancements needed in OPNET Modeler to be more suitable for the simulation of ZigBee WSNs are discussed.
