In this paper, we present analytical models for the average packet service time, end-to-end delay and system capacity for the p-persistent 802.11 MAC protocol. Models for both the "no retry limit" and "finite retry limit" cases are presented. The analytical models are validated by extensive simulation results. The advantage of the P-persistent 802.11 MAC protocol over the legacy 802.11 MAC protocol in providing throughput differentiation is illustrated.
