Title
Enhancing channel assignment performance in wireless mesh networks through interference mitigation functions
Abstract
The notion of Total Interference Degree (TID) is traditionally used to estimate the intensity of prevalent interference in a Multi-Radio Multi-Channel Wireless Mesh Network (MRMC WMN). Numerous Channel Assignment (CA) approaches, link-scheduling algorithms and routing schemes have been proposed for WMNs which rely entirely on the concept of TID estimates. They focus on minimizing TID to create a minimal interference scenario for the network. In our prior works [1] and [2], we have questioned the efficacy of TID estimate and then proposed two reliable interference estimation metrics viz., Channel Distribution Across Links Cost (CDAL <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">cost</inf> ) and Cumulative X-Link-Set Weight (CXLS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">wt</inf> ) which are proven effective in both Grid and Random WMNS [3]. In this work, we assess the ability of these interference estimation metrics to replace TID as the interference-minimizing factor in a CA scheme implemented on a grid MRMC WMN. We carry out a comprehensive evaluation on ns-3 and then conclude from the results that the performance of the network increases by 10–15% when the CA scheme uses CXLS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Wt</inf> as the underlying Interference Mitigation Function (IMF) when compared with CA using TID as IMF. We also confirm that CDAL <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">cost</inf> is not a better IMF than TID and CXLS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Wt</inf> .
