Abstract :
This paper presents a novel, simple yet accurate analytical model for the IEEE 802.15.4 contention access period MAC protocol. The model is based on a three-level renewal process, which leads to a general analytical framework applicable for the protocol variants of either single or double sensing, in a saturated or unsaturated case, under a general traffic arrival distribution. The analytical model is used to obtain some important performance metrics, such as MAC throughput and average frame service time. The accuracy of the analytical model is demonstrated by extensive simulation results.
