Group-Aware Stream Filtering

In this paper the authors are concerned with disseminating high-volume data streams to many simultaneous context-aware applications over a low-bandwidth wireless mesh network. For bandwidth efficiency, they propose a group-aware stream filtering approach, used in conjunction with multicasting, that exploits two overlooked, yet important, properties of these applications: Many applications can tolerate some degree of "Slack" in their data quality requirements, and there may exist multiple subsets of the source data satisfying the quality needs of an application.
