Abstract
An improved medium access protocol is divided into two tasks: collision avoidance and contention resolution. The purpose of the collision avoidance is to avoid occasional collisions due to the synchronization of channel access among different stations. The purpose of contention resolution is to control the overall sending rate of competing stations when the shared channel is operating at or near its capacity limits, such that excessive collisions can be avoided. Contention resolution methods in accordance with the present invention include a graceful rate control mechanism.
