This the 11th issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems
contains five selected papers focusing on Advanced Data Stream Management and Processing of
Continuous Queries. The contributions cover different methods for avoiding unauthorized access
to streaming data modeling complex real-time behavior of stream processing applications
comparing different event-centric and data-centric platforms for the development of
applications in pervasive environments capturing localized repeated associative relationships
from multiple time series and obtaining uniform and fresh sampling strategies over input data
streams generated by large open systems containing malicious participants.
