Abstract
Researchers and scientists have been studying Aloha networks for many years hoping to improve the channel throughput and overcome the inherent instability. In this study, we are going to describe some of the Aloha network features. An application of the slotted Aloha network is considered for local/mobile radio communications. The near/far effect, Rayleigh fading, and shadow fading arise in local/mobile radio communications due to differences in distances and topography between each of the users and the base station. These various effects cause a packet capture effect which improves overall channel throughput but leads to different packet delay times for the various users. An analysis of a ring model for local/mobile radio communications with correct packet capture is considered in this paper. The correct packet capture effect of one-ring and three-ring networks are studied. A Markov model is developed for a slotted Aloha network with capture. It is shown that the throughput in such a network is markedly greater than the standard 1/e. Perhaps even more important is the result that such networks are more stable under overload. .
