Abstract

Each node or link of an ad hoc network assists in the distributed allocation of a data channel to increase fairness, even in a multi-hop network, by tracking a measure of link weight for itself and sharing this information over a control channel with neighboring nodes. The metric can be provided over a dedicated control channel, added as a header to data communication on a data channel, or inferred by monitoring data traffic from the neighboring node. The link weight can be adjusted by a link quality factor based on provided or inferred metrics such as transmission rates, ratio of transmission errors, idle time, etc. For multiple flow queues at a subject node, one with a higher transmission rate can be selected for increased fairness. When a packet is received, medium access includes allocating bandwidth, including bonding multiple frequencies that are determined to be available to both nodes.
