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

Artikel i vetenskaplig tidskrift, 2006

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 Pij, the mean number of customers M̄, and the mean waiting time W̄. Performance comparisons between the IVth model and the IInd model are also presented.
