Abstract	Classical WMNs work in single-radio single-channel (SR-SC) architecture in which one network interface card (NIC) is deployed in each router and one common radio channel is shared by every mesh router. In this architecture, network endures from low capacity and throughput due to frequent back offs and packet collisions, hence single-radio multiple-channels (SR-MC) had been designed to enhance the WMNs performance. In SR-MC architecture every mesh router has to switch between channels dynamically with varying traffic load in the network, while integrating with adjoining mesh nodes to assure exchange of information for some period of time through a common channel but such coordination can be achieved by tight time synchronism among mesh nodes, but in a multihop WMNs it is difficult to achieve such synchronization among nodes. An adequate solution to reduce the high latency and simultaneously enhance throughput, reduce jitter and packet drop ratio of WMNs is to use Multi-Radio Multi-Channel (MR-MC) architecture. In MR-MC WMNs architecture, numerous communications can happen at the same time, and different channels assigned to adjoining links can carry data packets without interference. After implementing SR-MC WMNs and MR-MC WMNs in Qualnet simulator, results are evaluated based on parameters like throughput, jitter and packet receive ratio. Results show the significant difference between these two scenarios. MR-MC WMN provides the better result as compare to the SR-MC WMN. MR-MC WMN is much more suitable for the disaster management in the broadband internet application.
