本文分析了一种特别复杂的场景的拓扑和形态对ZigBee无线传感器网络部署的影响。这个复杂的场景是一辆汽车。损失机制的存在，如材料吸收(座椅、仪表盘等)，以及由于大量障碍物和金属环境(车身)而导致的强大多径组件的存在，以及对车辆内无线系统日益增长的需求，强调了配置异类车内无线系统的重要性。测量结果以及室内三维射线发射算法的仿真结果表明，这种复杂的场景对车载无线传感器网络的整体性能有很大的影响。结果还表明，ZigBee是一种成功部署车内无线传感器网络的可行技术。
In this paper, the influence of the topology and morphology of a particularly complex scenario on the deployment of ZigBee wireless sensor networks is analyzed. This complex scenario is a car. The existence of loss mechanisms, such as material absorption (seats, dashboard, etc.), and strong multipath components due to the great number of obstacles and the metallic environment (bodywork), as well as the growing demand for wireless systems within a vehicle, emphasize the importance of the configuration of heterogeneous intra-car wireless systems. Measurement results, as well as simulation results by means of an in-house three-dimensional ray-launching algorithm, illustrate the strong influence of this complex scenario on the overall performance of the intra-car wireless sensor network. Results also show that ZigBee is a viable technology for successfully deploying intra-car wireless sensor networks.
