An Evaluation of Media-Oriented Rate Selection Algorithm for Multimedia Transmission in MANETs

We focus on the optimization of real-time multimedia transmission over 802.11-based ad hoc networks. In particular, we propose a simple and efficient cross-layer mechanism that considers both the channel conditions and characteristics of the media for dyna ...

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, ...

Scalable position-based multicast for mobile ad-hoc networks

Jörg Widmer

In this paper we present Scalable Position-Based Multicast (SPBM), a multicast routing protocol for ad-hoc networks. SPBM uses the geographic position of nodes to provide a highly scalable group membership scheme and to forward data packets with a very low ...

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. ...

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 ...

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 ...

Contention-based forwarding for street scenarios

Jörg Widmer

In this paper, we propose to apply Contention-Based Forwarding (CBF) to Vehicular Ad Hoc Networks (VANETs). CBF is a greedy position-based forwarding algorithm that does not require proactive transmission of beacon messages. CBF performance is analyzed usi ...

A novel forwarding paradigm for position-based routing (with implicit addressing)

Jörg Widmer

Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is ...

Equilibrium Analysis of Packet Forwarding Strategies in Wireless Ad Hoc Networks - the Static Case

Jean-Pierre Hubaux, Mark Felegyhazi, Levente Buttyan

In multi-hop wireless networks, every node is expected to forward packets for the benefit of other nodes. Yet, if each node is its own authority, then it may selfishly deny packet forwarding in order to save its own resources. Some researchers have propose ...
