A Markov-modulated Bernoulli process (MMBP) is a mathematical framework used to describe the state of a system over time, where a binary state (either success or failure) is determined by the environment of the system, which evolves randomly over time according to a discrete-time Markov chain. In this paper, we present an MMBP-based mathematical modeling and analysis for evaluating the performance of the slotted Aloha random access protocol from both terminal and network perspectives. In particular, we investigate channel usage patterns in the presence of fading and present a unified analytic approach that benefits from the MMBPbased modeling. Through numerical studies, we verify the efficacy of our analysis.
