Abstract

In this paper, we present the design and throughput performance of a multiaccess protocol applicable to fully connected and homogeneous High Speed Radio LANs. The protocol utilizes a slotted message channel and an independent busy tone channel. The messages constitute multiple data packets and each packet occupies one slot duration. To study the throughput performance of the protocol a simulation model has been developed for Bernoulli arrivals and Geometric distribution of message lengths. The results show that while the propagation & processing delays degrade the throughput increasingly with the 'Delay Constant'-a factor equal to the smallest integer greater than or equal to the ratio between the two way radio propagation & processing delays to the packet duration-the protocol still is found to offer good throughputs of the order of 0.4 - 0.7 for Radio LANs up to 100 Mbps rate and 10 Kms range.
