Traffic engineering, as its name, is the art of manipulating traffic around so that traffic from congested links is moved onto the unused capacity on the other links. So, providing traffic engineering support in multi-hop wireless network has become increasingly important due to the low bandwidth nature of wireless channels. In this work, we propose a novel approach to control the traffic to avoid congestion by decoupling forwarding process from the routing process. The proposal is interested in provisioning quality of service guarantees for planned Wireless Mesh Networks which are being used widely as a broadband wireless access network.
