摘要： 针对某些应用的高可靠性要求，设计并实现适合无线传感器网络（WSN）应用的多路径可靠路由协议。该路由协议通过建立备份路径，并在主路径失效的情况下采用备份路径传输数据的方法来提高数据传输的可靠性。该协议主要包括节点局部拓扑信息的获取、路由请求、节点主干路径的建立、Sink或中间节点发送路径增强信息建立备份路由、主路径失效后启用备份路径发送数据过程。仿真测试结果表明，该多路径可靠协议在主干路径失效的情况下，可以有效减小路径断裂引起的丢包现象，进而提高网络整体数据传输的可靠性。

Abstract: To address the high reliability requirements of data transmission on certain applications，this paper designs and implements a Multi-path Routing Protocol（MRR），which is suitable for wireless sensor network applications.This protocol improves the reliability of data transmission by creating and using a backup data transmition path when the main path is not available.It consists of getting local node topology information，building node main routing，using sink or intermediate nodes to establish backup routing path routing of information.Test results based on TinyOS platform show MRP can effectively reduce the data package loss caused by broken path under the circumstances of main path failure，so it can improve the overall network reliability of the data transmission.
