摘　　要：无线传感器网络在一些应用中需要保证链路的可靠性,但由于传感器节点资源有限、通信链路不对称等特点,很容易导致数据链路发生变化.多径路由机制通过数据链路冗余的方式有效提高了数据链路的可靠性.在典型多径路由算法HEED的基础上,结合移动代理技术,通过建立备用数据链路并确定其优先级,设计了一种基于移动代理技术的多径路由机制MAHEED,使得无线传感器网络数据传输的可靠性得到明显提升.Wireless sensor networks aim to guarantee the reliability of the link in some applications, but limited sensor nodes and the asymmetry of communication links exist in the wireless sensor networks, which often leads to the changes in the data link. Multi - path routing mechanism helps improve the reliability of the data link effec- tively through data link redundancy. Based on the typical multipath routing algorithm HEED, with an application of the mobile agent technology and the establishment of the backup data link and the determination of its priority, this paper designs a MAHEED, and the reliability of data transmission of the wireless sensor network improves obviously.
