An Edge Computing-Based Complex Event Processing Technique for Sensor-Based Systems
Amarjit Singh Dhillon · 2018
Complex Event Processing (CEP) on sensor-based systems often uses a mobile gateway agent to forward raw sensor data streams to a remote back-end server.Complex events that are triggered by multiple raw events are then detected at the back-end server.This approach relies on a persistent network connection between the back-end server and the mobile device.This thesis proposes an edge computing-based mobile CEP technique in which CEP is performed on the mobile edge device using an embedded CEP engine and the detected complex events are sent to the back-end server for further processing.A proof-of-concept prototype for this system has been built using a Siddhi CEP engine and a WSO 2 server.A thorough performance analysis is performed for comparing the proposed system with the back-end server-based system.The proposed system can handle intermittent network disconnections and leads to reduced user cost and energy consumption for the mobile device."No problem can be solved from the same level of consciousness that created it" -Albert EinsteinThe work presented in this dissertation would not have been realized without the assistance of many individuals.I take this opportunity to express my sincere gratitude to everyone who helped me during this journey.Foremost, I would like to thank my supervisors Dr. Shikharesh Majumdar and Dr. Marc St-Hilaire for their continuous guidance, motivation, and feedback throughout the process.Secondly, I would like to thank my parents for providing me with monetary support and moralistic encouragement
