Research ArticleOpen accessIn the abstractComparative Study between Various Topological Models of Base Stations in Cellular Mobile Radio CommunicationMohammed F. AlhunaityIn this paper, we analyze the different parameters of quality for the network models of base stations (BS) when the service messages have not a delay. Also, we compare between four topologies star, ring, radial ring and fully connected using identical quality of user service and conditional cost of one Erlang. Our results have been obtained for different probabilities of … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,876 accessesView PDF Cite
