Real Time Complex Event Processing And Stream Reasoning for Low-Cost IoT Systems.

In IoT applications, data are continuously generated and must be processed in real-time to react to state changing in the environment where devices are deployed. Processing data as generated from sources is inefficient because of the low level of data. In this paper, we propose a generic Complex Event Processing system with reasoning abilities using the Waziup IoT Gateway(WaziGate) for LoRa based communication and low level data preprocessing. This must take into account cost constraints and internet connectivity issues that may exist in certain locations. This proposition is evaluated with two case studies: a fire detection system and a biological wastewater treatment system.
