Abstract

This correspondence presents HYMAP, a hybrid multiple access protocol for local area networks. The protocol combines features of both CSMA/CD and a collision-free protocol. Control is transferred from one protocol to the other according to state information sensed on the channel. The performance of HYMAP is evaluated by computer simulation for both data and voice packets. It compares favorably to other well-known multiple-access protocols. The number of packet-voice terminals that can be supported by HYMAP is higher than that obtained by using other protocols. Statistical analysis of the simulation results is also given.
