Securing Wireless Mesh Networks

Jean-Pierre Hubaux, Naouel Ben Salem

Using wireless mesh networks to offer Internet connectivity is becoming a popular choice for wireless Internet service providers as it allows fast, easy, and inexpensive network deployment. However, security in WMNs is still in its infancy as very little a ...

Performance Analysis of Self Limiting Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

Self limiting epidemic forwarding is a method of epidemic information dissemination in wireless ad-hoc networks that achieves congestion control by limiting spread (i.e. the number of nodes that receive a given message) and injection rate in order to prese ...

Coalition Formation in MANETs

Georgios Theodorakopoulos, Tao Jiang

Wireless ad-hoc networks rely on the cooperation of participating nodes for almost all their functions. However, due to resource constraints, nodes are generally selfish and try to maximize their own benefit when participating in the network. Therefore, it ...

Joint rate and power control algorithms for wireless networks

Ali H. Sayed

There is a fundamental tradeoff between power consumption, data transmission rates, and congestion levels in a wireless network. These three elements influence the performance of rate and power control strategies, and they need to be coordinated judiciousl ...

Power Control is Not Required for Wireless Networks in the Linear Regime

Jean-Yves Le Boudec

We consider the design of optimal strategies for joint power adaptation, rate adaptation and scheduling in a multi-hop wireless network. Most existing strategies control either power and scheduling, or rates and scheduling, but not all three together as we ...

Secure positioning of wireless devices with application to sensor networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Alamouti space-time coded relay strategy for wireless networks

Ali H. Sayed

A relay strategy for Alamouti space-time coded transmissions is proposed. The relay structure is optimized to maximize the received SNR and the receiver is able to exploit the orthogonal structure of the code to ensure temporal and spatial diversity ...

Multi-relay strategy for imperfect channel information in sensor networks

Ali H. Sayed

This paper describes a multi-relay strategy for wireless networks and examines the influence of imperfect channel information on system performance. A modified relay scheme is proposed to compensate for such imperfections. ...

Information-Theoretic Upper Bounds on the Capacity of Large Extended Ad Hoc Wireless Networks

Emre Telatar, Olivier Lévêque

We derive an information-theoretic upper bound on the rate per communication pair in a large ad hoc wireless network. We show that under minimal conditions on the attenuation due to the environment and for networks with a constant density of users, this ra ...

Self-Policing Mobile Ad-Hoc Networks by Reputation

Jean-Yves Le Boudec, Sonja Buchegger

Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. To cope with misbehavior in such self-organized networks, nodes need to be able to automatically adapt their strategy ...
