引入权重信息改善Ad Hoc网络路由协议的设计方法

Design Approach on Importing the Weight Information to Improve the Routing Protocol on Ad Hoc Network

由于Ad Hoc网络自身的特点,使其路由协议比传统的有线网络更为复杂.本文在分析了AODV路由协议及提出对其进行改善的AODV-BR路由协议的工作原理后,对AODV-BR中的备份节点从通信能力的角度,根据节点的传输速率和发包时延,引入了权重的度量标准,对AODV-BR协议进行了改善.仿真结果表明,该方法是有效的,它缩短了由于主路径断裂,目标节点接收到数据包的时刻与源接点发送数据包时刻之间的延迟,保证了通信质量.

Because of the self-characters in Ad Hoc network, its routing protocol is more complex than traditional ones. The paper first analyzes the principles of the AODV and the AODV-BR which is used to improve the former one, and then brings forward the weight information according to the communication ability of the backup nodes by packet transmission rate and delay in ad hoc network to improve the AODV-BR protocol. The simulation results show that the approach is effective. It shortens the delay between the destination node receiving the packets and the source node sending the packets because of the primary route broken and also guarantees the communication quality.
