An access control protocol using instantaneous bandwidth reconfiguration

A random access protocol is presented for multiaccess broadcast bus systems. Unlike previous algortihms which operate over a fixed set of channels (usually one), this protocol has the capability to reconfigure the available bandwidth instantaneously. It can thus present a more efficient channel configuration to the users subject to local loading conditions. As a result, the protocol achieves better delay throughput characteristics than the best available static or quasi-static allocation protocols. Simulation results are presented indicating the relative performance of the proposed protocol.
