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 …

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

This work focuses over the performability analysis of a multi-server retrial queueing model
with phase-type inter-retrial times in cellular networks. It is considered that the pattern 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 paper, we investigate the impact of retrial phenomenon on loss probabilities and
compare loss probabilities of several channel allocation schemes giving higher priority to …

Most studies of modern cellular mobile networks concern performance measures directly
computable from the stationary state probabilities such as the blocking probability and the …

In cellular networks, dropped calls and blocked calls can be a problem. This problem can be
mitigated if the network service is optimized. Service optimization can be achieved by …

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 consider a multiphase queuing system of type M/M/1/k→∙/M/1/k→⋯→∙/M/1/k with an
arbitrary number of nodes and a common retrial queue of type∙/M/1/k for other queues in the …

A multi-server retrial queue with two types of calls (handover and new calls) is analyzed.
