Human Exposure to Close-Range Resonant Wireless Power Transfer Systems as a Function of Design Parameters

In this study, human exposure to close-range wireless power transfer (WPT) systems operating in the frequency range 0.1-10 MHz with coil diameters up to 150 mm are investigated. Approximation formulae, which include scaling factors derived from numerical s ...

Near-optimal Sensor Placement for Signals lying in a Union of Subspaces

Martin Vetterli, Juri Ranieri, Dalia Salem Hassan Fahmy El Badawy

Sensor networks are commonly deployed to measure data from the environment and accurately estimate certain parameters. However, the number of deployed sensors is often limited by several constraints, such as their cost. Therefore, their locations must be o ...

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 ...

Exchanging Pairwise Secrets Efficiently

Christina Fragouli, Suhas Diggavi, Iris Safaka

We consider the problem where a group of wireless nodes, connected to the same broadcast domain, want to create pairwise secrets, in the presence of an adversary Eve, who tries to listen in and steal these secrets. Existing solutions assume that Eve cannot ...
