A unified local Markov model of a multihop packet radio network

A unified local Markov model of an S-ALOHA multihop packet radio network with an automatic repeat request (ARQ)-type station-to-station transmission protocol is formulated to study the joint impact of the buffer, acknowledgment, and retransmission policy on the network performance. The accepted symmetry assumptions permit focus on a single station in isolation, for which a set of stochastic equations is obtained and solved via hybrid simulation to obtain credible estimates of the desired steady-state characteristics. Sample results and comparisons are presented.
