In this paper, we investigate the impact of retrial phenomenon on loss probabilities and
compare loss probabilities of several channel allocation schemes giving higher priority to …

We consider a queueing model with N channels and an orbit with infinite waiting positions to
model a specific cell in wireless networks. It is assumed that handoff and new calls have …

We consider the MAP1, MAP2/M/c/∞, K retrial queue with two types of calls, retrial group of
finite capacity and geometric loss. This model is quite general enough to cover most of the …

Retrial queueing models have been applied to evaluate the impact of new and handover
calls on the call control mechanisms of cellular mobile networks. The fact that the retrial rate …

In this study, we extend upon the model by Haring et al.(2001) by introducing retrial
phenomenon in multi-server queueing system. When the most g number of guard channels …

A multi-server retrial queue with two types of calls (handover and new calls) is analyzed.
This queue models the operation of a cell of a mobile communication network. Calls of two …

We study a channel borrowing scheme applied in a cellular radio (personal communication)
system where call queueing and cutoff priority for handoff calls, which can improve the …

The retrial phenomenon and its significant effect on network performance have been taking
into account in the literature (eg, random access protocols in computer networks, cellular …

We consider an M/G/1 priority retrial queueing system with two types of calls which models a
telephone switching system and a cellular mobile communication system. In the case that …

The blocking probability of originating calls and forced termination probability of handoff
calls are important criteria in performance evaluation of integrated wireless mobile …
