摘要
为提高无线抄表系统数据传输的可靠性,提出了面向无线抄表应用的路由算法。双向的路由建立算法使网络中所有节点建立了最优的上下行路由,登记了完整邻居表以便于路由维护;基于Hello报文的邻居交换机制,及时发现网络拓扑结构变化,解决了网络中节点灵活出入网的问题,OMNeT++仿真结果验证了该路由算法的可靠性和有效性,满足无线抄表应用需求。
To improve the data transmission reliability of wireless meter reading system,a routing algorithm is proposed.The bidirectional routing algorithm is developed to make all nodes in the network establish optimal routing and register a complete neighbor table for routing maintenance.The neighbor exchange mechanism based on Hello Packet can timely detect changes in network topology and solve the problem that nodes flexibly comes in and out of the network.The simulation results of OMNeT ＋ ＋ verify the reliability and usefulness of the algorithm which can satisfy the need of wireless meter reading application.
