Abstract:

Recent advancements in the Internet, web and communication technologies cut across many areas of modern‐day living and enabled interconnection of every physical object, including, sensors and actuators. Web‐enabled smart objects empower innovative services and applications for different domains and improve utilization of resources. In this paper, we propose an interoperable Internet‐of‐Things (IoTs) platform for a smart home system using a Web‐of‐Objects (WoO) and cloud architecture. The proposed platform controls the home appliances from anywhere and also provides the homes’ data in the cloud for various service providers’ applications and analysis. Firstly, we proposed a Raspberry PI based gateway for interoperability among various legacy home appliances, different communication technologies, and protocols. Secondly, we bring the smart home appliances to the web and make it accessible through the Representational State Transfer (REST/RESTful) framework. Thirdly, we will provide the cloud server for smart homes’ to store the homes’ data due to low storage capabilities at a gateway and provide the data for various application’s service providers and analysis. In the proposed smart home platform, we implement a water‐tank control using Zigbee communication, an automatic door security using a normal camera as an IP camera, and provide web connectivity to different home devices for web‐based controlling. We aim to reduce the human intervention, secure access control to home devices from anywhere, provide smart homes data for application services as well as for analysis, and improve the utilization of resources.

5. Conclusion and Future Work

In this paper, we presented an interoperable Internet‐of‐Things platform for smart home system using WoO and cloud. The proposed architecture provides the interoperability among the legacy devices and communication protocol, and also provides access interface for user to access home devices from anywhere. We provided RESTful based smart home system to assign a unique URI to each sensor data and actuator event to reduce the processing at webserver. It will also provide interoperability among devices. In proposed architecture, we provide the web access to home legacy devices through the smart home gateway. The gateway provides interoperability among legacy devices such as water pump and tank control, lights and fan control, and the door security control. Moreover, the gateway aggregates sensors and actuators data, and stores it on the cloud for application services and for user’s history. Using the HTTP communication, the web application serving as a web client that provides user interface to check and alter the user home appliances status. This new idea is developed and tested for different functionalities of smart home services. Furthermore, the architecture can be extended to various smart building scenarios such as factories, offices, and smart grids etc.
