一种基于链路质量的移动Ad-hoc网络地理路由算法
Geographic Routing Algorithm Based on Link Quality in Mobile Ad-hoc Networks
摘要
Abstract
How to implement the simple routing mechanism enables nodes transfer the packets efficiently within a shorter time is a basic problem in research of the mobile Ad-hoc networks. According to the deficiencies of high bit-error rates and anti-interference technique, link quality was proposed as the new metric for route selection and a geographic routing algorithm based on link quality called LQPR was designed and implemented in this paper which solves the problem of a downward trend of packet delivery ratio on Non-ideal wireless link by using traditional greedy algorithm. The LQPR algorithm, which combines the LQ mode and Perimeter mode, guides data forwarding by use of the geographic information obtained by the location techniques, which has such advantages as less control overhead,optimal path selection and efficient transmissioa The proposed routing protocol LQPR was simulated by NS-2. Through evaluating and comparing the result in term of average end-to-end delay,aggregate throughput and delivery success rate,the validation of LQPR was then carried out with simulating data.关键词
