Toward plasma drifts in EMC3: Implementation of gradient, divergence, and particle tracing schemes

Matthieu Benoit C. Jacobs

This paper presents a first implementation of gradient, divergence, and particle tracing schemes for the EMC3 code, a stochastic 3D plasma fluid code widely employed for edge plasma and impurity transport modeling in tokamaks and stellarators. These scheme ...

Sensor Fault Tolerance in Output Feedback Nonlinear Model Predictive Control

Colin Neil Jones, Andrea Alessandretti

This paper presents an active output feedback fault-tolerant model predictive control (MPC) scheme for systems with sensor faults. The proposed control scheme actively steers the system in order to prevent loss of observability caused by a sensor fault. To ...

Hierarchical Routing Over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

The topology of a mobile wireless network changes over time. Maintaining routes between all nodes requires the continuous transmission of control information, which consumes precious power and bandwidth resources. Many routing protocols have been developed ...

On lattice codes for Gaussian interference channels

Michael Christoph Gastpar, Jingge Zhu

The usefulness of lattice codes is investigated for two-user Gaussian interference channels (IC). A coding scheme based on the compute-and-forward technique is shown to achieve the capacity region of the Gaussian IC under strong interference. The proposed ...

Creating Secrets out of Erasures

Christina Fragouli, Suhas Diggavi, Panagiotis Kostopoulos

Current security systems often rely on the adversary's computational limitations. Wireless networks offer the opportunity for a different, complementary kind of security, which relies on the adversary's limited network presence (i.e., that the adversary ca ...

Lattice codes for many-to-one cognitive interference networks

Michael Christoph Gastpar, Jingge Zhu

In this work we consider the cognitive many-to-one interference network. We first extend existing coding schemes from the two-user case to this network scenario. Then we present a novel coding scheme using compute-and-forward and show it can enlarge the ac ...

Bringing Stability to Wireless Mesh Networks

Adel Aziz

Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...

Evolution of Cache Replacement Policies to Track Heavy-Hitter Flows

Marco Canini

Several important network applications cannot easily scale to higher data rates without requiring focusing just on the large traffic flows. Recent works have discussed algorithmic solutions that trade-off accuracy to gain efficiency for filtering and track ...

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 ...

Secure incentives to cooperate for wireless networks

The operating principle of certain wireless networks makes essential the cooperation between the mobile nodes. However, if each node is an autonomous selfish entity, cooperation is not guaranteed and therefore we need to use incentive techniques. In this t ...
