Distributed complex event processing for mobile large-scale video applications

A recent trend in communication networks---sometimes referred to as fog computing---offers to execute computational tasks close to the access points of the networks. This enables mobile Complex Event Processing (CEP) middlewares to significantly reduce end-to-end latencies and bandwidth usage by migrating operators when event sources and consumers change their location. This demonstration shows the impact of proactive migration strategies on the perceived end user quality in the context of a video monitoring application.
