Abstract:

Aloha-type retransmission control policies have been proposed recently by Hajek and Van loon which can be implemented on a random access channel with ternary or binary feedback. They have shown that such schemes achieve a stable throughput of 1e .3678 for an infinite-population Poisson arrival model, by using simple first-order recursive retransmission policies. We drive measures of the speed of convergence and steady state accuracy for the local model of these policies. Using these measures, we compare two first-transmission policies, namely IFT and DFT. We extend the policies to cover the SuccessFailure binary feedback case, which is not covered in the work cited. Finally, we study the effects of channel errors on the performance of the random access system.
