改进的网络服务资源定位算法

Improved Algorithm for Web Service Resource Location

针对对等网络中Chord模型的不足,以网络资源定位为研究对象,将减少资源定位的等待时间作为改进目标,在分析现有解决思路和方法的基础上,引入双向路由机制和考虑后继节点列表的路由选择机制。针对模型的改变,对原有路由方法、稳定机制和路由信息的维护方法进行修改,并加以实现。模拟实验证明,与原算法相比,该改进资源定位算法减少了资源定位的等待时间。

This paper puts forward an improvement goals for the Chord model, such as reducing query waiting time, and analyzes the existing ideas and methods to achieve these goals. It introduces the bidirectional routing mechanism into the new algorithm and takes the successors list into the consideration of the next route hop chosen mechanism. Simulation result shows the algorithm has less queries waiting time than the original algorithm.
