Community-Based M2M Framework Using Smart/HetNet Gateways for Internet of Things

In order to manage the Internet of things in a flexible and efficient way, this paper proposes a novel M2M framework using smart/HetNet gateways. Our approach is not only compatible to the M2M standard, but also enables the community-based coordination among gateways and devices. With smart and HetNet gateways, various types of requirements and applications can be fulfilled and handled at a local region. Accordingly, unnecessary network usage is avoided so as to reduce the traffic loads in mobile networks. We also implement a prototype to sustain an application scenario of IoT. In our prototype, the lamp is automatically switched on when a human face is detected. The demonstration shows that our system is practical and supports the subscription and notification in a community. Finally, experimental results reveal that some basic procedures can benefit from the shorter time and less uplink traffic if devices involved in an application are within the same region.
