Network coding for efficient communication in extreme networks

Jean-Yves Le Boudec, Jörg Widmer

Some forms of ad-hoc networks need to operate in extremely performance- challenged environments where end-to-end connectivity is rare. Such environments can be found for example in very sparse mobile networks where nodes ”meet” only occasionally and are ab ...

On Selfish Behavior in CSMA/CA 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 can be dangerous, since the nodes themselves control their random defer ...

Joint Synchronization, Routing and Energy Saving in Multi-hop Hybrid Networks

Jean-Pierre Hubaux, Dan Jurca

Multi-hop hybrid networks can help providing both high bandwidth and broad coverage for wireless data networks. We focus on CSMA/CA-based networks and take IEEE 802.11 as a concrete example. We show that the three fundamental operations of synchronization, ...

Optimal Power Control, Scheduling and Routing in UWB Networks

Jean-Yves Le Boudec

Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...

Collaborative algorithms for bandwidth and rate allocation in wireless networks

Ali H. Sayed

We propose resource allocation strategies for a class of wireless networks with a clustering protocol. The nodes are assumed stationary and establish connections with the master node according to a priority scheme that relates to their distances from the m ...

Last Encounter Routing under Random Waypoint Mobility

Matthias Grossglauser, Natasa Sarafijanovic-Djukic

Last Encounter Routing (LER) algorithms for mobile ad hoc networks rely only on encounter histories at every node to route packets, and therefore do not need control traffic to track topology changes due to node mobility. LER exploits the fact that past in ...

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 ...

Base Stations in Mobile Ad-Hoc Networks

Thomas Lochmatter

Multi-hop ad-hoc networks consist of nodes which cooperate by forwarding packets for each other to allow communication beyond the power range of each node. In pure ad-hoc networks, no additional infrastructure is required to allow the nodes to communicate. ...

Poster: Contention-based distance-vector routing for mobile ad-hoc networks

Jörg Widmer

Position-based routing protocols forward packets in a greedy manner from source to destination without having to maintain routes through the network. Contention-based routing strategies improve upon position-based routing in that they do not even require t ...
