Abstract :
In this letter, performance of sliding frame (SF) R-ALOHA protocol for real-time mobile ad hoc wireless networks is investigated analytically and by simulation. A discrete Markov chain and Monte Carlo modeling are constructed to evaluate dynamic behavior of the protocol in transient state including distribution and mean of the system stabilization time (SST), and the average number of successful terminals. Capture effects on the SF R-ALOHA in the presence of multipath and shadowing are also addressed by the Markov chain analysis. The results reveal dynamic characteristics of the SF R-ALOHA system, and also show effectiveness and correctness of the developed models
