A power and rate control algorithm for wireless networks with state-delayed dynamics

Ali H. Sayed

A robust algorithm is developed for jointly controlling the power and rate of flow in a distributed wireless network. The dynamics of the network is modelled as a discrete-time state-delayed system with uncertainties and the proposed algorithm achieves bet ...

SOWER: Self-Organizing Wireless Network for Messaging

Jean-Pierre Hubaux, Mark Felegyhazi, Srdan Capkun

Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet many consumers consider that the price cellular network operators charge for it is too high. In this paper, we explain that there ...

Mobility Friendly Publish/Subscribe

Rachid Guerraoui

This paper describes an event dissemination algorithm that implements a topic-based publish/subscribe abstraction in mobile ad-hoc networks (MANETs). Our algorithm relies on (1) the mobility of the processes and (2) the validity period of the events to ens ...

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 ...

NASCENT: Network Layer Service for Vicinity Ad-hoc Groups

Jean-Pierre Hubaux, Jun Luo

Many envisioned applications of ad hoc networks involve only small scale networks that we term Vicinity Ad-hoc Groups (VAGs). Distributed coordination services, instead of pairwise communications, are primary requirements of VAGs. Existing designs for dist ...

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 ...

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 ...

A stochastic power control algorithm for wireless networks

Ali H. Sayed

In this paper, we propose a power control strategy for distributed wireless networks by using a quadratic state-space control design. Simulation results show the effectiveness of the proposed power control algorithm. ...

Secure Link State Routing for Mobile Ad Hoc Networks

Panagiotis Papadimitratos

The secure operation of the routing protocol is one of the major challenges to be met for the proliferation of the Mobile Ad hoc Networking (MANET) paradigm. Nevertheless, security enhancements have been proposed mostly for reactive MANET protocols. The pr ...
