MMC: Multiple metric cost routing metric for wireless mesh networks

There has been rapid growth in the area of wireless communication by Wireless Mesh Networks (WMNs) where routing metric is the key metric to find the optimized route in WMNs. For obtaining optimal performance, integrating multiple performance metrics into a routing protocol is effective, as single metric will not be able to satisfy the thorough requirement of WMNs. This paper has proposed a new routing metric for Multiple Metric Cost (MMC), WMNs, incorporating three metrics: Residual energy 2) Available Bandwidth and 3) Expected Transmission Count (ETX). MMC results in a better throughput. We evaluated the performance of MMC for proactive, reactive and opportunistic routing protocols using the OMNET++ network simulator. Our evaluation shows that MMC performs well in all three classes of routing protocols.
