Performance of wireless mesh networks (WMNs) in terms of network capacity,end-to-end latency, and network resilience depends upon the prevalent levels ofinterference. Thus, interference alleviation is a fundamental design concern inmulti-radio multi-channel (MRMC) WMNs, and is achieved through a judiciouschannel assignment (CA) to the radios in a WMN. In our earlier works we havetried to address the problem of estimating the intensity of interference in awireless network and predicting the performance of CA schemes based on themeasure of the interference estimate. We have proposed reliable CA performanceprediction approaches which have proven effective in grid WMNs. In this work,we further assess the reliability of these CA performance prediction techniquesin a large MRMC WMN which comprises of randomly placed mesh routers. We performexhaustive simulations on an ns-3 802.11n environment. We obtain conclusiveresults to demonstrate the efficacy of proposed schemes in random WMNs as well.
