Gateway Load Balancing in Wireless Mesh Networks

Gateway nodes are most important in Wireless Mesh Networks (WMNs) as most of the traffic is forwarded through them. As a result of this imbalance in the network condition may occur if one gateway becomes overloaded (through which maximum flow is forwarded) and some become underutilized. We propose one Gateway Load Balancing Algorithm (GWLBA) which is a distributed load-balancing protocol where gateways co-ordinate and exchange information about network condition and reroute traffic from congested gateways to underutilized ones. Our approach takes interference into consideration along with load balancing. We have simulated our approach using ns-2 .We have compared our scheme with some other schemes and shown that our scheme is better than them.
