Abstract
We analyze the MAC performance of the IEEE 802.15.4 LR-WPAN with non-beacon mode and non-saturated condition in a star topology. Our approach is to model stochastic behavior of one device with both uplink and downlink traffic as a discrete time Markov chain. First, we propose an analytical model of a device with only downlink traffic. Then, by combining the model of a device with only uplink traffic in and one with downlink traffic in this paper, we obtain the performance measures such as throughput, packet delay, energy consumption and packet loss probability of a device with both uplink and downlink traffic. Our results can be used to find the optimal number of devices so as to satisfy QoS (quality of service) on delay and loss probability.
