Online reconfiguration of channel assignment in multi-channel multi-radio wireless mesh networks

Antony Franklin Athula Balachandran C Siva Ram Murthy
Efficient utilization of Multi Channel–Multi Radio (MC–MR) wireless mesh networks (WMNs) can be achieved only by intelligent channel assignment (CA) and Link Scheduling (LS). Due to the dynamic nature of traffic demand in WMNs, the CA has to be reconfigured whenever traffic demand changes, in order to achieve maximum throughput in the network. The reconfiguration of CA requires channel switching at radios which leads to disruption of ongoing traffic in the network. So, we have to consider this traffic disruption overhead ...
