A Distributed System for Answering Range Queries on Sensor Network Data
A distributed system for approximate query answering on sensor network data is proposed, where a suitable compression technique is exploited to represent data and support query an...

Differential forms for target tracking and aggregate queries in distributed networks
Consider mobile targets moving in a plane and their movements being monitored by a network such as a field of sensors. We develop distributed algorithms for in-network tracking an...
