An introduction to theories and applications in wireless broadband networks As wireless
broadband networks evolve into future generation wireless networks, it's important for …

The complementary characteristics of wireless cellular networks and wireless local area
networks (WLANs) make them suitable to jointly offer seamless wireless access services to …

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 …

An increasing demand for wireless access to packet-based services has, in turn, driven the
need for call admission control strategies to make network roaming more seamless. This …

Vertical handoff plays an important role to provide seamless connectivity for a mobile user in
an overlapped multinetwork environment. On the other hand in order to maintain network …

Users' preference of WLAN-access has potential effect on the performance of a UMTS cell
with underlying WLANs. In the models with complementary-WLANs, the hybrid users (ie …

Dropping probability of the call requests in the UMTS with integrated WLAN reduces
drastically if some portion of the WLAN bandwidth is kept reserved for the UMTS traffic. But …

In this paper, we model the two-tier heterogeneous hierarchical overlay wireless networks
as open networks of loss systems. With the help of a network topology aided analysis of the …

In this paper, we present an efficient data channel assignment (DCA) scheme for a mixed
cell (ie, a 3G cell with embedded WLANs). Our effort is essential to increase the data request …

Next generation wireless network is envisioned to be heterogeneous, integrating a wide
variety of wireless access networks with different coverage, capacity and mobility support. In …
