Neighbor Discovery in Wireless Networks and the Coupon Collector's Problem

Ramin Khalili

Neighbor discovery is one of the first steps in the initialization of a wireless ad hoc network. In this paper, we design and analyze practical algorithms for neighbor discovery in wireless networks. We first consider an ALOHA-like neighbor discovery algor ...

Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

Hierarchical Routing over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

Dynamic networks are those where the topology changes over time and therefore efficient routes need to be maintained by frequent updates. Such updates could be costly in terms of consuming throughput available for data transmission, which is a precious res ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Towards Reliable Broadcasting using ACKs

Patrick Thiran, Christina Fragouli, Mathilde Durvy

We propose a mechanism for reliable broadcasting in wireless networks, that consists of two components: a method for bandwidth efficient acknowledgment collection, and a coding scheme that uses acknowledgments. Our approach combines ideas from network codi ...

Spectrum Sharing Games of Network Operators and Cognitive Radios

Jean-Pierre Hubaux, Mark Felegyhazi, Julien Freudiger, Peter Marbach

Since the beginning of the 20th century, the wireless frequency spectrum has been carefully controlled by government regulators. In response to the recent advances in radio technology, the spectrum regulators have opened some parts of the available spectru ...

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

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

Of Malicious Motes and Suspicious Sensors

Rachid Guerraoui, Seth Gilbert

How efficiently can a malicious device disrupt communication in a wireless network? Imagine a basic game involving two honest players, Alice and Bob, who want to exchange information, and an adversary, Collin, who can disrupt communication using a limited ...
