Project : Low power, High performance IoT Networking Solution
Purpose Rapidly growing IoT (Internet of things) value will be 14.4 trillion for companies and industries world wide till 2022. Many forecaster said sensor network market reaches about 45% of the IoT market. It is necessary to research on the sensor networks technologies. Since hundreds million things connected to Internet, resource management is not easy for efficient communication. This research develops networking solution combining heterogeneous radio and drone to support various IoT Applications/Network
Contents Based on mathematical backgrounds suck as game theory, optimization theory, probability and engineering techniques that can be applied to various IoT platforms, this research develops IoT networking solutions combining theory and implementation.
- Developing low power networking solution using heterogeneous radio
Heterogeneous radios (Zigbee, Sug-ghz radio, WiFi, LTE, etc.) have various properties such as communication frequency, communication ranges, throughput, latency, reliability, etc.
Considering those properties, we develop low power IoT networking solution using heterogeneous radios.
- Developing low power, low latency, high performance network using drones
Drones have good mobility and can be use communication device when they are equipped with various radio hardwares.
Using those mobility and communication functions, we develop techniques to reduce network energy consumption and latency.
- Improving network performance based on integration of drones and various networks
It is difficult to satisfy various QoS requirements for various IoT application. Based on optimization theory, it is important to develop networking solution satisfying required QoS. To develop such networking solution, we utilize drones and heterogeneous radio.
- Developing infrastructure of high performance IoT network
Ultimately, we develop infrastructure for IoT network that satisfies various QoS of IoT applications. We will provide low power, low latency, high performance networking functions for incoming IoT era.
Expected Contribution In IoT network, it is important that many things communicate with each other with low power. By supplying low power IoT networking solution, we can enhance networking solutions’ competitiveness.
To solve networking problems in incoming IoT era, we can develop networking solutions supporting various QoS for many applications.
