Abstract
In this paper, a contention resolution scheme for an uplink contention channel in a wireless access network is presented, The scheme consists of a tree algorithm, namely the identifier splitting algorithm (ISA), combined with a polling scheme. initially, ISA is used, but at a certain level of the tree, the scheme switches to polling of the stations. This scheme is further enhanced by skipping a few levels in the tree when starting the algorithm (both in a static and a dynamic way) and by allowing multiple instants simultaneously, An analytical model of the system and its variants leads to the evaluation of its performance, by means of the delay density function and the throughput characteristics, This model is used to investigate the influence of the packet arrival rate, the instant at which the ISA schemes switches to polling, the starting level of the ISA scheme, and the use of multiple instances on the mean delay, the delay quantiles, and the throughput.
