Self-Tuning, Bandwidth-Aware Monitoring for Dynamic Data Streams

Navendu Jain, Praveen Yalagandula, Mike Dahlin, Yin Zhang
2009 Proceedings / International Conference on Data Engineering  
We present SMART, a self-tuning, bandwidth-aware monitoring system that maximizes result precision of continuous aggregate queries over dynamic data streams.  ...  The primary challenge for SMART is how to dynamically select updates at each node to maximize query precision while keeping per-node monitoring bandwidth below a specified budget.  ...  ACKNOWLEDGMENTS We thank Joe Hellerstein, Adam Silberstein and the anonymous reviewers for their valuable feedback. Navendu Jain is supported by an IBM Ph.D. Fellowship.  ...

Towards collaborative data reduction in stream-processing systems

Ming Li, David Kotz
2009 International Journal of Communication Networks and Distributed Systems  
Our prototype-based evaluation shows that group-aware stream filtering is effective in trading CPU time for data reduction, compared with self-interested filtering.  ...  For bandwidth efficiency, we propose a collaborative data-reduction mechanism, 'group-aware stream filtering', used together with multicast, to select a small set of necessary data that satisfy the needs  ...  Acknowledgements This research program is a part of the Institute for Security Technology Studies  ...
