EXPECTED TRANSMISSION COUNT BASED STATIC CHANNEL ASSIGNMENT IN MULTI-RADIO MULTI-CHANNEL WIRELESS MESH NETWORKS

摘要

Wireless mesh networks with multi-radio multi-channel availability are attracting more and more attention from the research community due to its performance improvement.The goal of channel assignment in WMNs is to minimize interference.In this paper, we propose an integer quadratic programming (IQP) model to minimize the average network interference.Our model considers expected transmission count (ETX) of wireless link transmission, data transfer rate, power of nodes and so on.The simulation result shows it can promote throughput evidently, specifically, 20%~ 30% higher than throughput of other's.The feasibility and effect of the channel assignment model is suggested by the results of simulation.
