A survey on complex event definition languages in multimedia sensor networks

Abstract

A multimedia sensor network is a sensor network that consists of at least one sensor outputting multimedia data (video, audio, etc.). This kind of sensor network is a fairly new research domain. Hence, techniques for processing complex events in the context of multimedia sensor networks remain underdeveloped as they have rarely been considered previously. In this paper, we identify the requirements of a suitable language for processing complex events in multimedia sensor networks. The requirements are illustrated here through a motivating scenario related to "Smart Home Automation" application. We thoroughly survey existing studies and discuss them with respect to the considered requirements. The conclusions show that no existing language can fully address all the necessary requirements. A discussion about the needed features for processing complex events in multimedia sensor networks is also given here.
