A Flexible/Scalable IoT Server Node testbed, from Gateway to Edge Computing. A Smart Home Use Case

This paper presents the approach for the design, implementation and testing of a low cost open technology flexible and scalable IoT Server Node. This node may be capable of supporting a variety of communication and protocol standards and it is also expandable in means of both storage requirements and processing power. The proposed IoT Server Node is based on a raspberry Pi board and additional communication boards. It is demonstrated with ZigBee IoT nodes based on Arduino board, controlled by an Android application.
