无线Mesh网络中基于干扰判定的LIM-HWMP路由协议
LIM-HWMP BASED ON JUDGING INTERFERENCE IN WIRELESS MESH NETWORKS
摘要
Abstract
As the traditional traffic model which uses Poisson distribution to describe the flow arrival process can not reflect the burst characteristics of network traffic,a traffic model using multiple ON /OFF nodes with heavy tailed distribution is built.And then the arrival process of the data stream is verified and analyzed to obey the Pareto distribution.The route metric LIM is calculated by the interference probability,channel competition degree,and physical interference model SINR.According to the LIM,the LIM-HWMP is proposed,which will select a path with smaller interference in the network with traffic burst characteristics to reduce the end to end delay.Through using the NS2 simulation software to simulate the HWMP and LIM-HWMP protocol,it is indicated that the advanced route protocol get both a certain improvement in the terms of the average end-to-end delay and the packet loss rate.关键词
