Solving the grand challenge using an opensource CEP engine.

ABSTRACTThe DEBS Grand Challenge is an annual event in which different event-based systems compete to solve a real-world problem. The 2014 challenge is to demonstrate scalable real-time analytics using high-volume sensor data collected from smart plugs over a one and a half month period. This paper aims to show how a general-purpose commercially available event-based system - the WSO2 Complex Event Processor (WSO2 CEP) - was used to solve this problem. In addition, we explore areas where we created extensions to the WSO2 CEP engine to better solve the challenge.
