基于工业无线网络性能评价的规划路径算法

摘要

针对路由节点查找消息路径的局限性,提出了一种网关设备规划消息路径的算法.该算法结合工业无线网络通信数据的规律性,在考虑时延、能耗、可靠传输和负载均衡方面的性能综合评价之后,找出一种路径组合,避免消息拥塞和干扰,提高通信性能.然后,设计了仿真实验来对比规划路径与AODV查找路径两种情况下的通信性能.实验结果证明,规划的消息路径下的通信性能更好.%Against limitations for routing nodes to lookup message routing, this paper brought forward an algorithm by which the gateway device plans the message paths. The algorithm combines the regularity of the industrial wireless network communication data, finds a path combination, after considering performance comprehensive evaluation in the delay, power consumption,reliable transmission,and load balance,in order to avoid messages' congestion and interference and improve communication performance. And then, a simulation was desighed to compare the paths with AODV and the paths planed overall. The simulation results show that overall planning the paths of messages can make the communication better.
