Abstract
Prioritizing traffic forwarding in a wireless mesh network. In a wireless mesh network using carrier detect multiple access—collision avoidance with backoff, such as mesh networks supporting IEEE 802.11 clients, access points in the mesh calculate a node rank based on downstream and upstream rank components. Access points in the mesh then generate backoff times inversely proportional to their node rank. This has the effect of prioritizing traffic at nodes that have higher rank. The downstream and upstream rank components take into account the amount of space occupied by downstream and upstream traffic, respectively, and are weighted by their position in the mesh tree.
