This paper proposes a methodology to analyse connectivity over highly heterogeneous
wireless networks. We consider a scenario comprising a large number of access elements …

In this paper we model access selection in heterogeneous access network environments as
a binary linear optimization problem. The model is based on a flexible utility function, which …

In this work we analyze the possibilities which are brought about by the use of linear
programming techniques in the framework of access selection procedures within …

Access selection is an important key in heterogeneous networks, and the design of a new
algorithm for decision is not a trivial task. Different aspects must be taken into consideration …

Wireless technology is a revolutionary advancement providing users with ubiquitous data
and telephony access anywhere and anytime with no physical (PHY) connection. The …

ldquoAlways Best Connectedrdquo (ABC) is a fundamental and challenging dimension of
the fourth generation heterogeneous wireless networks. In order to enable the ABC, access …

The selection of the most suitable radio access technology to serve as the communication
means for a service in a heterogeneous wireless access network is a complex task. It …

The rapid development and integration of heterogeneous wireless networks provide
ubiquitous communications for mobile users. The intelligent and multimodal mobile …

The aim of this thesis is to define a solution offering end-users seamless mobility in a multi-
radio access technology environment. Today an increasing portion of cell phones and PDAs …

Service delivery in a heterogeneous wireless network environment requires the selection of
an optimal access network. Indeed, the selection of a non-optimal network can result in …
