One emerging characteristic of electronic devices is the increasing number of connectivity interfaces (aka NICs1) towards the outside world. That obviously translates in a set of technical issues related to their management in order to provide seamless ...

Due to the increasing number of IEEE 802.11 networks, the presence of interference is becoming an important problem to solve. In a single multicell network, the harmful effect of interference is minimized thanks to network planning; but if there are ...

The rising popularity of wireless devices opens exciting possibilities for users to share their resources. However, there exists no end-to-end, general-purpose, resource sharing framework for such devices. Existing resource sharing solutions address ...

In this paper we describe the UniWireless framework, a nationwide distributed Open Access testbed that involves different research units collaborating in the TWELVE national project. The Uni-Fy AAA system, used to manage the collection of involved ...

Wireless LAN (WLAN) is rapidly growing as a popular technology for ubiquitous communication, where Internet access is being a standard commodity. The growing demand in WLAN technological development is to provide high quality and secure Internet access ...

In most current systems, managing access to networks rely on static rules implemented on firewalls and IDS (Intrusion Detection Systems). These measures lack a systematic consideration of the context within which an attack occurs. Indeed, we argue that ...

Hotspot services will be offered in small, highly-populated public places like airports, hospitals, etc. They will play their assistive roles in the people's life only if they are secure, trusted, and nonobtrusive. Some of the challenges faced are the ...

VoIP is born from the growing Internet infrastructure, which has over the years seen significant improvements in both bandwidth and end-to-end latency. In this paper, we explore making VoIP available on a mobile phone. For that purpose, we propose an ...

IEEE 802.11 Wireless Local Area Network (WLAN) became a prevailing technology for the broadband wireless Internet access, and new applications such as Voice over WLAN (VoWLAN) are fast emerging today. For the battery-powered VoWLAN devices, the standby ...

The task of forming a route can be broken into two parts, finding any route to the desired host and refining that route so it is suitable for the conenction. We refer to this first task as paging and it consists of simply delivering a single packet to ...

In this paper, we propose assistive service provision architecture in pervasive environments. This architecture is based on a distributed approach and ensures service design, deployment and discovery aspects. In order to perform those aspects, several ...

We present a localized IP auto-con.guration protocol for wireless ad-hoc networks, called OASIS. OASIS introduces the idea of position-dependent IP-addresses using a cellular structure of the underlying network. Within a cell, nodes try to obtain a ...
