Mathematical modelling for the contention-collision elimination access mode of the Ⅳth system model to a multiple star LAN

摘要

The contention-collision elimination access mode is a new kind of access mode in star LAN. It can be divided into six different models according to the working principle. The mathematical analysis and performance evaluations for the Ⅰst, Ⅱnd, Ⅲrd and Ⅴth models have been presented in our previous papers. The performance evaluation for the Ⅳth model is discussed in this paper by calculating several important parameters in steady-state i.e. the customer's transfer probability P_(ij), the mean number of customers M, and the mean waiting time W. Performance comparisons between the Ⅳth model and the Ⅱnd model are also presented.
