Cognitive Radio Through Primary Control Feedback

Michael Christoph Gastpar

A fundamental problem in dynamic frequency reuse is that the cognitive radio is ignorant of the amount of interference it inflicts on the primary license holder. Policies that attempt to limit interference without the active participation of the primary ar ...

Efficient Model Checking of Fault-Tolerant Distributed Protocols

Johannes Kinder

To aid the formal verification of fault-tolerant distributed protocols, we propose an approach that significantly reduces the costs of their model checking. These protocols often specify atomic, process-local events that consume a set of messages, change t ...

Castor: Scalable Secure Routing for Ad Hoc Networks

Karl Aberer, Panagiotis Papadimitratos, Marcin Poturalski, Wojciech Galuba, Zoran Despotovic

Wireless ad hoc networks are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach that ad ...

Ultra Low Power Communication Protocols for UWB Impulse Radio Wireless Sensor Networks

Jérôme Rousselot

This thesis evaluates the potential of Ultra Wideband Impulse Radio for wireless sensor network applications. Wireless sensor networks are collections of small electronic devices composed of one or more sensors to acquire information on their environment, ...

Joint Identity-Message Coding for Sensor Networks

Christina Fragouli, Suhas Diggavi, Lorenzo Keller, Mahdi Jafari Siavoshani

In a significant class of sensor-network applications, the identities of the reporting sensors constitute the bulk of the communicated data, whereas the message itself can be as small as a single bit—for instance, in many cases, sensors are used to detect ...

Method for wireless transmission between two electroacoustic transducers, and device for carrying out said method

Michel Declercq, Patrick Favre

The invention relates to a method and a device for wireless transmission between at least one first transducer (T1) arranged in a first location and at least one second transducer (T2) arranged in a second location remote from the first location without us ...

Securing Every Bit: Authenticated Broadcast in Radio Networks

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Zarko Milosevic

This paper studies non-cryptographic authenticated broad- cast in radio networks subject to malicious failures. We in- troduce two protocols that address this problem. The first, NeighborWatchRB, makes use of a novel strategy in which honest devices monito ...

The Next 700 BFT Protocols

Rachid Guerraoui, Marko Vukolic, Nikola Knezevic

Modern Byzantine fault-tolerant state machine replication (BFT) protocols involve about 20,000 lines of challenging C++ code encompassing synchronization, networking and cryptography. They are notoriously difficult to develop, test and prove. We present a ...

From Centralized to Distributed Sensor Localization

Amin Karbasi

In this work we consider the problem of sensor localization when only the connectivity information is available. More specifically, we compare the performance of the centralized algorithm MDS-MAP with its distributed version HOP-TERRAIN. We show that both ...

Mobility-centric design of collaborative transportation systems

Embedded sensors and actuators are revolutionizing the way we perceive and interact with the physical world. Current research on such Cyber-Physical Systems (CPSs) has focused mostly on distributed sensing and data gathering. The next step is to move from ...
