Smart home platform based on optimized wireless sensor network protocol and scalable architecture

In this paper, we propose a smart home platform based on optimized wireless sensor network (WSN) protocol and scalable architecture. In this platform, system environment is divided into two main environments, indoor and outdoor. Outdoor environment uses internet-cloud system, while indoor environment uses WSN system. This scheme is also well known as Internet-of-Things (IoT) concept. Those two environments are connected to each other by using access point bridge. WSN system is established from efficient and scalable WSN components. Each component of WSN is designed to use an optimized protocol. WSN components are connected to each other in mesh topology in order to provide scalable architecture for further extension and changes. For outdoor environment, the existing internet-cloud system is used as infrastructure. Thus, this smart home platform can be monitored and controlled from smart phone, anytime and anywhere, as long as mobile data access is provided. For databasing implementation, SQLite database system is chosen because of its low cost and easy configuration. For system evaluation, several tests have been conducted to deliver the profile of proposed system.
