摘要： 由于无线传感器网络路由协议对于影响数据传输因素的考虑不够全面，本研究利用层次分析法将无线传感器路由过程层次化分解，对路由过程中的路径长度、数据完整性、能量消耗、接收延时4个影响因素进行分析。通过对不同传输路径的相对优劣进行排序，从而达到优化路由选择的目的。仿真结果分析表明，该方法可以更全面地考虑影响路由的因素，比指南针方法所得到的路径在能量消耗、数据完整度、传输延时等多个方面都要优越。

Abstract:  Because the influence in the wireless sensor network routing protocol for data transmission factor of consideration is not comprehensive. Using the analytic hierarchy process. wireless sensor routing process is decomposition, Path length in the process of routing, data integrity, energy consumption, receiving delay four influencing factors were analyzed. The relative merits of different transmission path were sorted to achieve the purpose of optimized routing. The results of simulation analysis shows that the method can consider the factors, affecting the routing much more fully than the compass method of path in energy consumption, data integrity, transmission delay.

Key words:  wireless sensor network; analytic hierarchy process; data transmission; path selection; optimization algorithm
