On Cheating in CSMA/CA Ad Hoc Networks

Jean-Pierre Hubaux, Imad Aad, Mario Cagalj

CSMA/CA protocols rely on the random deferment of packet transmissions. Like most other protocols, CSMA/CA was designed with the assumption that the nodes would play by the rules. This is important, since the nodes themselves control their random deferment ...

Algebraic-geometric codes on the erasure channel

Mohammad Amin Shokrollahi, Andrew Brown

This paper investigates the use of algebraic-geometric codes for data transmission over a packet network, by comparing their encoding/decoding speeds to those of the ubiquitous Reed-Solomon Codes. We take advantage of the fact that AG codes allow the const ...

End-to-end congestion control for tcp-friendly flows with variable packet size

Jean-Yves Le Boudec, Jörg Widmer, Catherine Boutremans

Current TCP-friendly congestion control mechanisms adjust the packet rate in order to adapt to network conditions and obtain a throughput not exceeding that of a TCP connection operating under the same conditions. In an environment where the bottleneck res ...

A Test-Bed for Misbehavior Detection in Mobile Ad-hoc Networks - How Much Can Watchdogs Really Do?

Jean-Yves Le Boudec, Cédric Tissières, Sonja Buchegger

Several misbehavior detection and reputation systems have been proposed for mobile ad-hoc networks, relying on direct network observation mechanisms, so-called watchdogs. While these approaches have so far only been evaluated in simulations and restricted ...

Hierarchical location service for mobile ad-hoc networks

Jörg Widmer

Position-based routing has proven to be a scalable and efficient way for packet routing in mobile ad-hoc networks. To enable position-based routing, a node must be able to discover the location of the node it wants to communicate with. This task is typical ...

Low-density parity-check codes with rates very close to the capacity of the q-ary symmetric channel for large q

Mohammad Amin Shokrollahi

Transmission of packets over computer networks is subject to packet-level errors, which appear as "bursts" of bit-level errors and are not well modeled by memoryless binary channels. A standard scrambling technique is used for transmission of packets by th ...

Packet Selection and Scheduling for Multipath Video Streaming

Pascal Frossard, Dan Jurca

This paper addresses the problem of choosing the best streaming policy for distortion optimal multipath video delivery, under delay constraints. The streaming policy consists in a joint selection of the video packets to be transmitted, as well as their sen ...

Explicit window-based transport control protocols in lossy environments

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses efficient packet loss recovery by retransmission in window-based congestion control protocols. It builds on explicit congestion control mechanisms to decouple the packet loss detection from the congestion feedback signals. Implicit alg ...

Measurement and Analysis of Single-Hop Delay on an IP Backbone Network

Patrick Thiran

We measure and analyze the single-hop packet delay through operational routers in the Sprint Internet protocol (IP) backbone network. After presenting our delay measurements through a single router for OC-3 and OC-12 link speeds, we propose a methodology t ...

Secure Message Transmission in Mobile Ad Hoc Networks

Panagiotis Papadimitratos

The vision of nomadic computing with its ubiquitous access has stimulated much interest in the Mobile Ad Hoc Networking (MANET) technology. However, its proliferation strongly depends on the availability of security provisions, among other factors. In the ...
