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 the planning of modern cellular mobile communication systems, the impact of customer
behavior has to be carefully taken into account. Two models dealing with the call retrial …

We consider a multi-server queueing system with two types of customers operating in the
Markovian random environment. Under the fixed state of the random environment, the arrival …

Many of the currently used cellular networks have been constructed on the premise that the
retrial phenomenon is negligible and the operating environment is static. However, a proper …

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 …

Generally in call centers, voice calls (say Type 1 calls) are given higher priority over e-mails
(say Type 2 calls). An arriving Type 1 call has a preemptive priority over a Type 2 call in …

In this paper, we consider an MMPP/M/1/1 retrial queue where incoming fresh calls arrive at
the server according to a Markov modulated Poisson process. Upon arrival, an incoming call …

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