A Fair Scheduling for Wireless Mesh Networks

Jean-Pierre Hubaux, Naouel Ben Salem

Wireless Mesh Networks (WMNs) represent a new and promising paradigm that uses multi-hop communications to extend WiFi networks: By deploying only one hot spot (directly connected to the Internet) and several transient access points (TAPs), an Internet Ser ...

Reputation-based Wi-Fi Deployment

Jean-Pierre Hubaux, Naouel Ben Salem

Wi-Fi networks have a very strong potential: They are easy to deploy, they use unlicensed frequencies and they provide Internet connectivity that is several times faster than by cable modem. However, two major problems still need to be solved: the lack of ...

Reputation-based Wi-Fi Deployment - Protocols and Security Analysis

Jean-Pierre Hubaux, Naouel Ben Salem

In recent years, wireless Internet service providers (WISPs) have established thousands of WiFi hot spots in cafes, hotels and airports in order to offer to travelling Internet users access to email, web or other Internet service. However, two major proble ...

Improving availability with recursive microreboots: a soft-state system case study

George Candea

Even after decades of software engineering research, complex computer systems still fail. This paper makes the case for increasing research emphasis on dependability and, specifically, on improving availability by reducing time-to-recover. All software fai ...

DOMINO: A System to Detect Greedy Behavior in IEEE 802.11 Hotspots

Jean-Pierre Hubaux, Imad Aad, Maxime Raya

The proliferation of hotspots based on IEEE 802.11 wireless LANs brings the promise of seamless Internet access from a large number of public locations. However, as the number of users soars, so does the risk of possible misbehavior; to protect themselves, ...

Fuelling WiFi deployment: A reputation-based solution

Jean-Pierre Hubaux, Naouel Ben Salem

The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. However, the lack of unified roaming slows down the de ...

A multiple core mode for protocol independent multicast

Francesc Font Torre de Mer

Internet communications have traditionally been based on point-to-point connections. This technique is called unicast and allows one sender and one receiver to communicate. The Internet saw the appearance of multicast protocols in the early 90's. Multicast ...

A Cooperative Backup System

Sameh Mohamed Elnikety

We present a novel peer-to-peer backup technique that allows computers connected to the Internet to back up their data cooperatively: Each computer has a set of partner computers, which collectively hold its backup data. In return, it holds a part of each ...

JAGR: an autonomous self-recovering application server

George Candea

This paper demonstrates that the dependability of generic, evolving J2EE applications can be enhanced through a combination of a few recovery-oriented techniques. Our goal is to reduce downtime by automatically and efficiently recovering from a broad class ...

The provision of a low delay service within the best-effort Internet

Paul Hurley

In this work, we define a novel Internet service, called ABE (Alternative Best-Effort), which allows interactive multimedia applications to receive low queuing delay within the existing best-effort Internet. We then develop and analyse a number of innovati ...
