基于递归算法的最短跳数路径的RSS测距算法
RSS Ranging Algorithm for the Shortest Path Based on Recursive Function
摘要
Abstract
In multi-hop wireless networks,location-based applications require an accurate localization algorithm.To locate sensors at a low cost,recursive function shortest path-based RSS ranging(RFSPR) algorithm is proposed.The RFSPR algorithm employs the recursive functions to find all possible paths with the minimum number of hops between a source sensor and a destination sensor.Then the distance among the shortest path is estimated by received signal strength(RSS).Finally the average value of all the shortest path distances is taken as a distance estimate.The proposed algorithm is analyzed and compared with classical algorithms.Numerous simulation results show that the RFSPR algorithm provides distance estimates with low estimation error.关键词
