Internet is widely used in the fast growing world. So the wired and wireless networks are mainly used in an active area and there are many limitations in the wireless mesh network. The Congestion Control in the Network field is by means of Scheduling packets from different traffic flows for processing at a specific node is done. In Wireless Adhoc Network, a channel assignment has to balance the connectivity and aggregate bandwidth. In order to increase the maintaince, we use channel assignment algorithm. This algorithm is used to assign the channels to the network interfaces from the given expected load on each virtual link. In the existing work , there is no combined solution of multi-channel assignment with routing and congestion control. In this paper, we propose an efficient multi channel allocation and congestion control technique for wireless mesh networks. The frequency channels are assigned according to the congestion measure which indicates the congestion status at each link. Depending on the selected congestion measure i.e. queuing delay, packet loss probability and differential backlog and various design objectives can be achieved. Our proposed algorithm is simple to implement as it requires each node to perform a local search. Unlike most of the previous channel assignment schemes, our proposed algorithm assigns not only the non-overlapped frequency channels but also the partially-overlapped channels. This technique uses traffic aware metic to provide quality of service and it comprises requirements on all the aspects of connection such as service response time, loss, signal-to-noise ratio, cross-talk, echo, interrupts, frequency response, loudness levels and so on. To overcome this problem, we use proposed technique which can improve throughput and channel utilization to very high extent because it provides solution for multi-channel assignment and congestion control. And also assigns the channels so that congestion is avoided and co-channel interference levels with same channel are reduced. In this paper, we evaluate high throughput and channel utilization along with reduced latency which can be implemented in the Adhoc Network. Thus the efficient channel allocation with congestion control technique for Wireless Mesh Network can be done using NS-2 Simulation tool for attaining high throughput and reduced latency. Thus the paper proposes an efficient channel allocation for Congestion Control in Adhoc Network.
