ABSTRACT:
A system and method for providing a traffic control scheme for QoS provision and congestion control across multiple interfaces of wireless nodes (102, 106and107), such as wireless access points (107and106), communicating in a wireless multihopping communication network (100). The nodes (102, 106and107) can include multiple transceivers. The system and method detects bottleneck interfaces in these nodes (102,106, 107) to control the traffic along the path of the corresponding traffic flow. Different measurements and cross-layer feedback are used to differentiate the cause of the congestion, such as wireless link quality degradation due to fading or degradation due to congestion in a shared medium. The nodes (102, 106, 107) inform each other on the status of their congestion level. High and low level signaling and interruption mechanisms are used to control the interfaces of the congested node (102, 106or107) to adjust traffic flow and alleviate the congestion.
