Energy-efficient graph-based wavelets for distributed coding in Wireless Sensor Networks
This work presents a class of unidirectional lifting-based wavelet transforms for an arbitrary communication graph in a wireless sensor network. These transforms are unidirectiona...

Adaptive distributed transforms for irregularly sampled Wireless Sensor Networks
We develop energy-efficient, adaptive distributed transforms for data gathering in wireless sensor networks. In particular, we consider a class of unidirectional transforms that ...

Tracing Stateful Pirate Decoders
Abstract— Most traitor tracing schemes in the literature assume that pirate decoders are stateless. This stateless assumption, however, is unrealistic especially in case of hardw...

Snoogle: A Search Engine for the Physical World
—Hardware advances will allow us to embed small devices into everyday objects such as toasters and coffee mugs, thus naturally form a wireless object network that connects the ob...

Secure Information Flow for Distributed Systems
We present an abstract language for distributed systems of processes with local memory and private communication channels. Communication between processes is done via messaging. Th...
