Anypath routing

Henri Julien Dubois-Ferrière

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. A well-known instance is with unreliable wireless links, where the probability that at least one node out ofnreceives a packet increas ...

Packet Combining in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

This paper presents the Simple Packet Combining (SPaC) error-correction scheme for wireless sensor networks. Nodes buffer corrupt packets, and when two or more corrupt versions of a packet have been received, a packet combining procedure attempts to recove ...

Single and Multi-Hop ARQ in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

We present a novel error-correction scheme for sensor networks called Multi-hop Hybrid ARQ (MHARQ). Rather than immediately discard a received corrupt packet, a node buffers it. When two corrupt versions of a packet have been received, a procedure attempts ...

Packetized Media Streaming with Comprehensive Exploitation of Feedback Information

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmission using acknowledgement feedback. The different transmission scenarios associated to a group of interdependent media data units ar ...

Fault-Tolerant Real-Time Streaming with FEC thanks to Capillary Multi-Path Routing

Emin Gabrielyan

Erasure resilient FEC codes in off-line packetized streaming rely on time diversity. This requires unrestricted buffering time at the receiver. In real-time streaming the playback buffering time must be very short. Path diversity is an orthogonal strategy. ...

Optimal FEC Rate for Media Streaming in Active Networks

Pascal Frossard, Dan Jurca

This paper addresses the problem of optimal channel rate allocation for media streaming in active networks, where intermediate nodes are able to perform basic FEC decoding/encoding operations. FEC performance is analyzed in the case of hop-by-hop FEC prote ...

Evaluation of a Routing Architecture for Wireless Messaging Ad-Hoc Networks

Mark Felegyhazi, Megha Goel

The Short Messaging Service(SMS) which has become very popular in cellular networks is very highly priced. We show in this paper how self-organizing ad-hoc networks can be used to provide the short messaging service, at a much lower price. We propose a rou ...

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 ...

Malice, Selfishness, and Slander in Mobile Ad-hoc Networks.

Jean-Yves Le Boudec, Sonja Buchegger

In mobile ad-hoc networks nodes need to cooperate to communicate, but there are many reasons for non-cooperation. Saving power or preventing other nodes from obstructing a service are merely selfish reasons for non-cooperation, whereas nodes may also activ ...

Scalable routing protocols with applications to mobility

Ljubica Blazevic

In this thesis we study two routing problems related to mobility. The first problem concerns scalable multicast routing when there is a large number of multicast groups with a small number of receivers. Existing dense and sparse mode routing protocols have ...
