Implementation of Home Automation System Using OpenHAB Framework for Heterogeneous IoT Devices Recent years has seen the growth in home automation industry as it becomes more accessible due to the increasing dependence on smartphones and smart devices. Despite this, problems in interoperability still exists due to the absence of standardized protocol in the application layer which prompts the user to be dependent on multiple applications to access and monitor several smart appliances. In this study, a home automation system was implemented using OpenHAB framework that is focused on the integration of different smart devices and backend technologies. Since most smart devices have different communication protocols, the focus of this work was on the development a smart home solution framework that is modular and flexible. In addition, this smart home framework utilized RESTful protocol to integrate smart devices such as smart bulb, smart plug, smart TV from various manufacturers and utilized MQTT protocol to integrate sensors based on ESP8266 that monitors the ambient condition of the room. Lastly, the study provides a comparative analysis on the developed smart home framework and the commercially available smart home solution by Samsung known as SmartThings. The study considered the comparison of these two frameworks in categories such as userfriendliness, security, and their degree of compatibility with various smart devices.

IoTBased Anonymous Authentication Protocol Using Biometrics in Smart Homes The smart home is increasingly being considered as one of the Internet of Things applications. With the development of mobile networks and the speed of data transfer, the expansion of smartphones and increasing of interest in raising the safety factor in personal life, many companies have entered the smartphone market. With the help of the Internet of things portal, it is possible to monitor wireless sensors and use noncomputerized alert systems. Therefore, it is essential to secure such a system to create a sense of relaxation in the lives of users and homeowners to deal with possible occurrences. The integration of technologies for the automation of home affairs with the Internet of things means that all physical objects can be accessed on cyberspace; therefore, the concerns raised by users about the lack of privacy and security are a serious argument that science and technology should answer. This paper proposes an anonymous secure framework in connected smart home environments, using solely lightweight operations. The proposed framework in this paper provides efficient authentication and key agreement, and enables devices (identity and data) anonymity and unlinkability. It is demonstrated that computation complexity of the proposed framework is low as compared to the existing schemes, while security has been significantly improved. The proposed scheme assures us that even if the home owneru0027s device is attacked, the rest of the system will continue to work properly.
