ABSTRACT:
In a network including multiple nodes communicating on a channel using CSMA protocol, where each node accesses the channel by occupying at least one time slot in a contention interval, the invention includes transmitting and receiving, in a node, messages on the channel during a first time interval. The invention counts, in the node, at least one of the transmitted and received messages during the first time interval. The invention determines, in the node, a channel occupancy during the first time interval, after counting the messages, and then adaptively adjusts, in the node, the contention interval based on the channel occupancy.
