Mobility management in wireless cellular networks is one of the main issues for resource
optimization. It is aimed to keep track of Mobile Stations (MSs) in the different Location Areas …

An improvement for the mutual authentication in the third-generation mobile networks is
proposed to address the potentially long delay in waiting for authentication vector (AV) when …

The sum of random variables are of interest in many areas of the sciences. In teletraffic
analysis, the sum of Hyperexponential distribution is used as a model for the holding time …

Handoff is an indispensable operation in wireless networks to guarantee continuous,
effective, and resilient services during a mobile station (MS) mobility. Handoff counting …

In this paper, we derive the distribution of the channel-holding time when both cell-residence
and call-holding times are phase-type distributed. Furthermore, the distribution of the …

In this paper, the performance of cognitive radio networks (CRNs) considering either
Poisson or ON/OFF models for the primary users' arrivals is evaluated and compared. These …

Call holding time (CHT) is a statistical indicator in a cellular network, directly affecting
network performance and providing critical insight for the network service provider. CHT …

In this paper, a teletraffic model to analyze wireless mobile cellular networks with hyper-
Erlang distributed cell dwell time is developed. We demonstrate that the residual cell dwell …

We study the characteristics of the channel holding time in the multitier cellular systems
supporting overflow and underflow schemes with the general call holding time and the …

In this paper, under the assumption that the unencumbered service time is exponentially
distributed, a novel algebraic set of general equations that examines the relationships …
