| 摘 要： | 为了提高无线传感器网络中数据传输的可靠性,设计了一种基于关键节点备份的多路径可靠路由协议（BK-MR-RP）.首先,采用侦听机制来获取邻居节点的路由信息,通过对链路质量和路径相关因子的综合评估选择一条或多条备用路径;其次,针对相关度较高的网络找出路径关键节点,采用节点备份技术对路径关键节点进行备份,以此提高数据传输的可靠性;最后,提出在数据包中添加多个附加位的方式来指示源节点选取的数据包发送的路径.仿真结果表明,随着网络中节点数目的增加,BK-MRRP协议使数据传输的成功率提高5％～10％,传输延迟降低10％ ～ 25％.

| Abstract: | In order to improve the reliability of data transmission in wireless sensor networks, a multi-path reliable routing protocol based on backup key nodes （BK-MRRP） is proposed. Firstly, interception mechanism is adopted to get routing information of neighbor nodes, and one or more alternate paths are selected through comprehensive evaluation of link quality and path correlation factor. Then, in order to improve the reliability of data transmission, path key nodes are found out for some high correlation network, and the path key nodes are backuped by using number of nodes, BK-MRRP protocol makes success rate of data transmission increase by 5 percent to 10 percent, and transmission delay reduces by 10 percent to 25 percent. |
