Ambient intelligence is an emerging discipline that brings intelligence to our everyday
environments and makes those environments sensitive to us. Ambient intelligence (AmI) …

Network-enabled sensing and actuation devices are key enablers to connect real-world
objects to the cyber world. The Internet of Things (IoT) consists of the network-enabled …

Pervasive computing environments such as smart spaces require a mechanism to easily
integrate, manage and use numerous, heterogeneous sensors and actuators into the …

Home automation systems, or Smart homes, offer a wide variety of functions. Some include
remotely controllable appliances, such as lights, doors, coffee machines, tempera ture …

We describe a new suite of computational benchmarks that models applications featuring
multiple levels of parallelism. Such parallelism is often available in realistic flow …

Modern stream applications such as sensor monitoring systems and publish/subscription
services necessitate the handling of large numbers of continuous queries specified over …

In this paper, we address the problem of continuous access control enforcement in dynamic
data stream environments, where both data and query security restrictions may potentially …

Multi-way stream joins with expensive join predicates lead to great challenge for real-time
(or close to real-time) stream processing. Given the memory-and CPU-intensive nature of …

In recent years, data streams have become ubiquitous as technology is improving and the
prices of sensor, location-tracking and portable devices are falling. Examples of streaming …

Database management systems (DBMSs) have been used successfully in traditional
business applications that require persistent data storage and an efficient querying …
