Abstract
The invention comprises adjustment of back-off timers to provide consistency of timing in a group of collaborating nodes.The invention facilitates optimizing access to a wireless medium in a communication network accessible by a plurality of nodes, each node implementing a back-off counting based on carrier sense multiple access with collision avoidance, the plurality of nodes comprising a collaborative group of nodes further implementing a back-off allocation scheme based on each node maintaining a list of expected back-off values of the other nodes of the collaborative group, the group further comprising a receiving node and an emitting node, reception of information from the emitting node being utilized by the receiving node to maintain consistency of timing through adjustment of back-off values.
