Retransmission control in mobile radio slotted Aloha

Abstract

For the slotted Aloha protocol in a mobile radio environment, a retransmission control scheme is proposed, and a rigorous analysis is developed to prove the stability of the resulting system. This analysis is shown to apply to virtually any model for the spatial distribution of the users. It is also shown that the use of retransmission control is unavoidable if the network performance predicted in the recent literature is to be achieved.<>
