Abstract
In this paper, we analyze the uplink performance of unsaturated slotted IEEE 802.15.4 medium access layer using the Markov chain model and the theory of M/G/1 queues. In our treatment the emphasis is paid to retransmission due to collision of packets, since it plays a very important role in the behavior of the slotted CSMA-CA algorithm. The validity of the proposed model is demonstrated by good agreements between the model results and Network Simulator 2 (ns-2) simulations.
