In this paper, we model an integrated system of cellular and wireless local area networks
(WLANs) with multi-rate traffic as an open network of Erlang loss systems. A network …

The main feature of the next generation wireless communication systems is the ability to
establish ubiquitous and seamless access to various radio access technologies (RATs) and …

As network providers implement multiple network types, including 2G/3G networks and
potentially 1G, wireless local loops (WLL), and/or satellite, it becomes feasible to overflow …

The rapid development and deployment of integrated heterogeneous networking
environments such as third generation (3G) cellular WANs and WLANs will soon become …

We present an analytic model for the performance evaluation of hierarchical cellular
systems, which can provide multiple routes for calls through overflow from one cell layer to …

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

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 …

In recent years, there has been an increased interest in the integration of different
technologies in heterogeneous environments. Modelling heterogeneous systems is a …

Mobility is one of the major issues in the performance characterization of wireless
communication systems. Wireless communication systems encounter failures. These failures …

This paper presents the analysis of integrated voice and data cellular networks with channel
borrowing. Our considered system gives higher priority to handoff calls over new calls from …
