Analysis of a class of star-interconnected networks

摘要

A certain class of multiuser communication networks interconnected according to a star topology is analyzed. A type of Markov modulated Bernoulli model is developed for the exact characterization of their output processes, and the mean packet delay induced by the interconnected scheme is obtained through an approximate analysis of the queueing system, which is formulated in the central node of the star topology. It is shown that Aloha multiuser communication networks belong in the investigated class of networks. Delay analysis of Aloha networks interconnected according to a star topology is carried out, and some numerical results are obtained. These results and those obtained under Bernoulli approximation on the network output processes are compared with simulations.
