  Abstract

In this paper, a new random access scheme is proposed to improve the probability of successful access. In the conventional scheme, a packet is transmitted by a user using one slot and considered successfully transmitted if a collision does not occur. In comparison, a packet of the proposed scheme is transmitted by a user using one or more slots and considered successfully transmitted if there is at least one slot without collision. We evaluate the optimal number of slots selected by users to maximize the probability of successful access when the probability distribution functions for the number of users are given such as Binomial and Poission distribution. From the numerical analysis, it is shown that the proposed scheme performs better than conventional scheme.
