Probabilistic model of data flow formation in wireless communication networks

A wireless communication network with a hierarchical star structure is considered as a queuing system. A topological scheme is proposed that contains a combination of several single-channel and one multi-channel queuing systems. Oriented graphs of queuing systems are composed. The formulas of probabilistic indicators of the network functioning efficiency are obtained. The estimation of the average time of the request presence in the system and the probability of the request failure are given.
