Exploiting Content-Based Pub/Sub Systems for Event Detection in Emergency Management

Emergency management needs to detect diverse events, covering non-spontaneous events and spatio-temporal events, and notify the related personnelas soon as possible so that they can make further decisions. This paper introduces how to carry out event detection and notification by exploiting content-based Pub/Sub systems, and it also summarizes our work progress in this field. Through describing our event detection language and its application examples, the paper demonstrates the event detection capability of our Pub/Sub systems. Furthermore, this paper explains subscription/event routing strategies employed in our Pub/Sub systems constructed in different network environments (including cloud and VANETs), and these strategies serve for dynamic load balance and efficient event notification, respectively.
