IoT architecture design for 6LoWPAN enabled Federated Sensor Network

Internet of Things (IoT) is an enhanced technology to extend the functionality of current WSNs from local to remote and from a small or large scale to a global scale. There are three solutions of integrating WSNs with the Internet including Front-End Proxy solution, Gateway solution and the TCP/IP Overlay solution. Every single solution has its own features and successful applications. In this paper, we first compare all these three solutions and then find out the most suitable one for the localization and tracking application. 6LoWPAN enabled Federated Sensor Network (FSN) is used to illustrate the IoT architecture and meet the application requirements. A real application is given to demonstrate the architecture and the design of the IoT system.
