Abstract: This paper presents a self-adaptive routing algorithm based on Bayesian estimation for Wireless Sensor Network(WSN), which solves the automatic adjustment of routing request zone. The algorithm sets the radius of cylindrical request zone as the parameter and makes use of Bayesian estimation to realize the self-adaptation of the routing request zone. The simulation results for packet delivery ratio, routing overhead, average packet delay, and residual energy ratio show this algorithm performes better than AODVjr.

摘要： 针对无线传感器网络中存在的路由请求域动态调整问题，提出一种基于Bayes估计的无线传感器网络自适应路由算法。该算法以圆柱形路由请求域的半径作为调整参数，利用Bayes估计对路由请求域进行自适应调整。仿真结果表明，该算法在数据包投递率、路由开销、数据包平均时延和网络剩余能量比率上的性能都优于AODVjr路由算法。
