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 ...

A Method and a system for energy consumption saving in wireless access networks

Dejan Kostic, Marco Canini

The method of the invention, comprising at the user side: a) checking if the load of a first gateway to which a user terminal device is wirelessly connected, falls below a given low load threshold; b) if said first gateway load has fallen below said given ...

Firmware for ensuring realtime radio regulations compliance in WSN

Pierre-André Farine, Alexis Boegli, Mitko Tanevski

All wireless devices must comply with the local radio regulations which are set by international and national regulatory bodies such as the European Telecommunication Standardization Institute (ETSI) for Europe and the Federal Commission for Communication ...

Reliable Physical Layer Network Coding

Michael Christoph Gastpar

When two or more users in a wireless network transmit simultaneously, their electromagnetic signals are linearly superimposed on the channel. As a result, a receiver that is interested in one of these signals sees the others as unwanted interference. This ...

Secure key exchange in wireless networks

Christina Fragouli, László Czap

We investigate the problem of exchanging a se- cret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret grou ...

Distributed Delay-Power Control Algorithms for Bandwidth Sharing in Wireless Networks

Nicolas Gabriel Gast

In this paper, we formulate a delay-power control (DPC) scheme for wireless networking, which efficiently balances delay against transmitter power on each wireless link. The DPC scheme is scalable, as each link autonomously updates its power based on the i ...

Information Theoretic Operating Regimes of Large Wireless Networks

Olivier Lévêque, Ayfer Özgür Aydin

In analyzing the point-to-point wireless channel, insights about two qualitatively different operating regimes --bandwidth- and power-limited-- have proven indispensable in the design of good communication schemes. In this paper, we propose a new scaling l ...

Interference Robustness and Security of Impulse-Radio Ultra-Wide Band Networks

Manuel Flury

In this thesis we study Impulse-Radio Ultra-Wide Band (IR-UWB), a physical layer radio technology offering many features that make it a promising choice for future short-range wireless networks. The challenges in such networks are many, ranging from the co ...

Self-Synchronizing Properties of CSMA Wireless Multi-hop Networks

Patrick Thiran, Olivier Dousse, Kuang Xu

We show that CSMA is able to spontaneously synchronize transmissions in a wireless network with constant-size packets, and that this property can be used to devise efficient synchronized CSMA scheduling mechanisms without message passing. Using tools from ...

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 ...
