Lightweight virtualization intelligent Iot Gateway design and implementation

Nowadays, the Internet has become not just a large network, but a platform for IoT systems where large and small units, from temperature sensors to refrigerators, can communicate with each other. IoT devices that make life easier can communicate not only with each other but also with end users. It is extremely critical that IoT units, which may have different communication protocols, can communicate with each other over the internet. For this, IoT Gateways are an important part of these systems. As IoT Gateways are used to transfer data from IoT systems to cloud systems, they can also be used to process and return the data they collect. In this thesis, an IoT Gateway that can exchange data between ZigBee Wireless Networks and IP Networks has been designed and implemented. This IoT Gateway System, which detects and analyzes sensor data coming from IoT objects or wireless sensor networks, keeps it in a database and can send/receive to end users in the IP network, is implemented on a single-board embedded with Linux operating system. The system can communicate with clients on the IP network with MQTT Web Service and Socket Programming. The backbone of the system is the application software named Sniffer.py developed in Python language. During the design and implementation of the IoT Gateway, the flexibility and innovations that Lightweight Virtualization will bring to the IoT Gateway - Edge Calculator applications were also tested. During the development and testing of the features of the developed Smart IoT Gateway, data obtained from ZigBee Sensor Networks created in the laboratory environment were used. The analysis results of IEEE802.15.4 frames received from the ZigBee network were compared and verified with Wireshark and TI SmartRF network traffic monitoring tools.
