Introduction

Main role

The laboratory is responsible for applying the latest technologies in the field of networking and communications (IoT, AI, mobile networks, new generation Internet, SDN programmable networks) in different application areas of life (agriculture, fisheries, health, etc.) to bring values and benefits to users.

Development history 

Initially, when equipment and facilities were not available, research activities were carried out only on simulation tools. From the period of 2016-2017, using laboratory-sponsored equipment, the research teams have become familiar with IoT and AI technologies to develop a number of prototype products within the laboratory. to practical applications like:

• IoT-based medical data collection system for monitoring and assisting respiratory disease diagnosis.
• AQI air quality measurement box and AQI collection system using MQTT protocol stack.
• Development of IPv6 CoAP / UDP / RPL / 6LoWPAN / 802.15.4 protocol stack on Contiki for ARDUINO UNO circuitry, aimed at smart city applications.
• Machine learning algorithm development based on the energy-saving stacking protocol of IoT CoAP / UDP / RPL / 6LoWPAN / TSCH to increase reliability, aiming at industrial applications.

From 2017 til now, the laboratory actively cooperates with foreign enterprises and large domestic technology corporations to research and develop products in the field of IoT and AI in agriculture and fisheries.

Main research specialization

IoT and new technologies.

AI and data processing in agriculture and fisheries.

Optical network and optical network optimization.
