The growing demand for high-speed wireless access to the Internet is the driving force behind the current trends to design All-IP wireless networks, whose Access Router and mobile stations use Internet Protocol for signaling and /or data transport. That will allow an ubiquitous IP-based access by mobile users, with special emphasis on the ability to use a(More)
Mobile users are facing the fact that many heterogenous radio access technologies coexist, ranging from wireless LANs to cellular systems. No technology has emerged as common and universal solution which makes the current trends today toward design of All-IP wireless networks, where radio cells are under the control of IP Access Routers for signalling and(More)

Handover is the process which allows the roaming of a mobile node between two access points. This roaming implies the momentary disconnection of the mobile node, and disruptions of current communications. Several handover mechanisms have been proposed for IP based protocosl. In this document, we show comparisons and analyses of these mechanisms. We evaluate(More)
This paper presents an overview of a software radio architecture for testing quality-of-service (QoS) aware IP data services over a typical third-generation radio interface. The testbed is implemented using a hard real-time micro-kernel known as RTLinux, running beneath the Linux operating system for providing real-time ene-to-end functionality. The testbed(More)
ABR was standardised by the ATM Forum in 1996. Source, destination and switch behaviours were specified. However, a lot of freedom was left to the switch manufacturers to implement an efficient algorithm compliant with the ABR specifications. There exists three different behaviours. Namely, they are binary switches, Relative Rate (RR) switches and Explicit(More)
