Resource Allocation Management in Multi-Radio Multi-Channel joint with Routing Protocol in ad-hoc Wireless Network

Channel bandwidth allocation management is one of the research issues in multi-channel multi radio interface wireless network, inappropriate selection of the channel leads to the probability of choosing congested channel which may not satisfy QoS requirement, it results in the significantreduction of the network performance, by increasing in delay and loss of the packets due to collisionbetween them. In this paper, we propose a mechanism that selects a channel based on lowestcomparable distributed expected bandwidth consumer. Network layer takes the decision for allocatingthe channel after receiving the information about the estimated bandwidth in each channel through its attached MAC layer in a cross layer manner. We consider a wireless network is multiple-hop with IEEE802.11 multi-radio channels interfaces. The efficiency and effectiveness of the proposed workhas been evaluated by NS-2 and a comparison has been made with random channel allocation. Simulation results show that our proposed work has clearly improved the network performance in terms of end-to-end delay and throughput
