GPS Improvement System Using Short-Range Communication

Many Internet of Things (IoT) applications have emerged in recent years. Although some variants exist, IoT systems are basically composed of many devices and servers and therefore require the development of both device-and server-side systems. This makes the development of IoT system difficult. In this paper, an IoT architecture is proposed that avoids this requirement, thereby simplifying the IoT system development. As an example of our proposed architecture, we present a Global Positioning System (GPS) improvement system from the device side only. Each device communicates with other devices to acquire more accurate GPS data. The accuracy of our GPS improvement system was verified with prototype application.
