- Performance Analysis of S-Aloha used as a random acces channel on mobile communications David Covarrubias Aldo Mendez Cesar Vargas Ingeniería This paper evaluates the effects of Rayleigh fading, shadowing, and spatial distribution of the Mobile Terminals(MTs) on the operating performance of Slotted Aloha (S-Aloha) used as a Random Access Channel (RACH). Thispaper also evaluates the capture probability in a channel exhibiting Rayleigh fading, shadowing, and the effect ofspatial distribution of the MTs. In addition, this work presents a different version of the steady-sate probabilities ofthe Markov chain of S-Aloha considering capture effect. This article simulates the stabilization of S-Aloha by utilizingan algorithm that dynamically controls the retransmission probabilities. Finally, this paper presents a numericalanalysis of these simulations and identifies the operating of parameters that have shown to degrade systemresponse. 2005 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47401101 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.1
