STA: Spatio-Temporal Aggregation with Applications to Analysis of Diffusion-Reaction Phenomena
Spatio-temporal data sets arise when time-varying physical fields are discretized for simulation or analysis. Examples of time-varying fields are isothermal regions in the sea or ...

Brief announcement: locality-based aggregate computation in wireless sensor networks
We present DRR-gossip, an energy-efficient and robust aggregate computation algorithm in wireless sensor networks. We prove that the DRR-gossip algorithm requires O(n) messages a...

Online Aggregation over Trees
Consider a distributed network with nodes arranged in a tree, and each node having a local value. We consider the problem of aggregating values (e.g., summing values) from all nod...
