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

Jean-Pierre Hubaux, Mark Felegyhazi, Levente Buttyan

Ad hoc networks are expected to be used in a number of very different situations. But a common characteristic is that the nodes have to cooperate with each other. This problem is particularly crucial, if each node is its own authority. Reckoning the releva ...

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 ...

FRANC: A Lightweight Java Framework for Wireless Multihop Communication

André Schiper, David Cavin, Yoav Sasson

Simulation and emulation are popular means for evaluating wireless Mobile Ad hoc Networks (MANETs) protocols. Since MANETs are highly dependant on their physical environment, these techniques offer only a partial understanding of factors that may influence ...

Self-organized public-key management for mobile ad hoc networks

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

In contrast with conventional networks, mobile ad hoc networks usually do not provide on-line access to trusted authorities or to centralized servers and they exhibit frequent partitioning due to link and node failures and to node mobility. For these reaso ...

Contention-based forwarding for mobile ad-hoc networks

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 ...

Why Max-min Fairness Is Not Suitable For Multi-Hop Wireless Networks

Jean-Yves Le Boudec

We consider the issue of which criteria to use when evaluating the design of a wireless multihop network. It is known, and we illustrate in this paper, that maximizing the total capacity, or transport capacity, leads to gross imbalance and is not suitable. ...

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

A non-line-of-sight equalization scheme for wireless cellular location

Ali H. Sayed

Among the challenging issues that affect the performance of wireless location techniques is the temporal and spatial variations of the channel, and the distribution of the scatterers, which introduce non-line-of sight errors at the base station. This paper ...

Rate Performance Objectives of Multi-hop Wireless Networks

Jean-Yves Le Boudec

We consider the question of what performance metric to maximize when designing ad-hoc wireless network protocols such as routing or MAC. We focus on maximizing rates under battery lifetime and power constraints. Commonly used metrics are total capacity (in ...
