Bringing physical layer cooperation closer to practical wireless systems

Nowadays the demand for communication over the wireless medium is significantly increasing, while the available wireless spectrum is already limited. In this thesis, we introduce new practical physical layer designs that employ node cooperation for more ef ...

SenseCode: Network Coding for Reliable Sensor Networks

Aikaterini Argyraki, Christina Fragouli, Lorenzo Keller, Emre Atsan

Designing a communication protocol for sensor networks often involves obtaining the right trade-off between energy efficiency and end-to-end packet error rate. In this article, we show that network coding provides a means to elegantly balance these two goa ...

Low cost security for sensor networks

Christina Fragouli, Lorenzo Keller, Iris Safaka, Emre Atsan

We design and evaluate a lightweight encryption protocol suitable for sensor networks, that enables weak security in the presence of passive eavesdroppers. At every communication round, our protocol creates a key between each sensor node and the sink, by a ...

Towards integrating Quantize-Map-Forward relaying into LTE

Christina Fragouli, Suhas Diggavi, Emre Atsan

We present a method to integrate the Quantize-Map-Forward (QMF) relaying scheme [1] into the standard LTE operation, for a two-relay diamond network configuration. Our approach implements QMF using mainly existing LTE modules and functionalities, and resul ...

On Relay Placement for Deterministic Line Networks

Christina Fragouli, Emre Atsan

We consider a unicast communication problem where, a source transmits information to a destination through a wireless network with the help of k relays positioned on a line. We adopt the linear deterministic model to capture the wireless signal interaction ...

SenseCode: Network Coding for Reliable Sensor Networks

Aikaterini Argyraki, Christina Fragouli, Lorenzo Keller, Emre Atsan

Designing a communication protocol for sensor networks often involves obtaining the "right" trade-off between energy efficiency and reliability. In this paper, we show that network coding provides a means to elegantly balance these two goals. We present th ...
