Wireless Mesh Networks Capacity Improvement Using Cbf

Wireless mesh network has recently received a great deal of attention as a promising technology to provide ubiquitous high bandwidth access for a large number of users. Such network may face a significant broadcast traffic that may consequently degrade the network reliability. In this paper, we have focused interest to wireless mesh network based IEEE 802.11s and we have designed a self-pruning method to control and reduce the broadcast traffic forwarding. Our scheme, namely Control of Broadcast Forwarding (CBF), defines two behaviours to manage the broadcasting operation. Routing packets are managed differently from data broadcast messages to avoid afflicting the routing process. The simulations results show that CBF ameliorates the network capacity by reducing considerably the number of redundant packets, improving the end to end delay and providing high reachability and packet delivery ration.
