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 …

Two-tier cellular networks consist of a group of contiguous microcells overlaid by a
macrocell. This design provides an enhanced use of the networks' resources for both high …

Handoff will become an increasingly important issue in mobile phone communications,
especially in microcellular systems with the increase of handoff traffic between cells. Many …

Handoff is an important issue in cellular mobile telephone systems. Recently, studies that
question the validity of the assumption of handoff arrivals being Poissonian have appeared …

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

We propose and analyze a handoff scheme for integrated real-time and non-real-time
service in wireless mobile network. The channels are divided into three parts, one is for real …

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 …

Mobility is one of the major issues in the performance characterization of wireless
communication systems. Various approaches exist in the literature for performance …

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 …
