Scalable delivery of stream query result

Yongluan Zhou, Ali Salehi, Karl Aberer
2009 Proceedings of the VLDB Endowment  
In this paper, we leverage Distributed Publish/Subscribe System (DPSS), a scalable data dissemination infrastructure, for efficient stream query result delivery.  ...  To take advantage of DPSS's multicast-like data dissemination architecture, one has to exploit the common contents among different result streams and maximize the sharing of their delivery.  ...  The data from each sensor are treated as one data stream. In the experiments, we use 63 streams as our data set and emulate the streaming scenario by using their timestamp information.  ...
