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.
Due to their “on demand ” nature, the reactive protocols for MANETs, incurred less overhead and hence are preferred over proactive protocols. Since reactive protocols rely on network wide flooding of routing messages, they suffer from the... more
Due to their “on demand ” nature, the reactive protocols for MANETs, incurred less overhead and hence are preferred over proactive protocols. Since reactive protocols rely on network wide flooding of routing messages, they suffer from the “broadcast storm ” problem. Received signal strength based probabilistic flooding scheme named RSS-GossipAODV was proposed in [13]as an attempt to solve the frequent link breakages and broadcast storm experienced in AODV routing protocol. This paper investigates the ability of RSS-GossipAODV to handle different node mobility speeds in faded and non-faded environments.The performance of RSS-GossipAODV is evaluated by varying node mobility speed. It is evident from our experimental results that in both non faded and Rician faded scenarios, RSS-GossipAODV outperforms conventional AODV in term of packet delivery ratio, throughput, delay and link breakages and at the same time tries to minimize the broadcast storm problem by flooding lesser number of ro...
