Spatiality in videoconferencing: trade-offs between efficiency and social presence
In this paper, we explore ways to combine the video of a remote person with a shared tabletop display to best emulate face-to-face collaboration. Using a simple photo application ...

Stability-throughput tradeoff and routing in multi-hop wireless ad hoc networks
We study the throughput of multi-hop routes and stability of forwarding queues in a wireless ad-hoc network with random access channel. We focus on a wireless network with static ...

Optimal Distortion-Power Tradeoffs in Sensor Networks: Gauss-Markov Random Processes
We investigate the optimal performance of dense sensor networks by studying the joint source-channel coding problem. The overall goal of the sensor network is to take measurements ...
