In this chapter, the IEEE 802.15.4 MAC layer is modeled using a per-node Markov chain model. Using this model, expressions for various performance metrics including delay, throughput, power consumption, and efficiency, are derived and such expressions are subsequently validated against the corresponding values obtained via simulation. The simplifying assumptions required by the Markov-chain analysis are studied and their impact on the performance metrics is quantified.
