Abstract :
An enhancement to the CSMA p-persistent protocol family is proposed, based on a fully decentralized control that adjusts the message transmission rate of each node to the estimated density of surrounding transmitting nodes. The system does not require enumeration of nodes nor control messages, the only input to the control coming from the physical medium occupation. Stability conditions are given in both cases of fixed and switching topologies. We show that good channel exploitation levels can be assured as well by suitably tuning the control parameters.
