Item Design, Specification and Implementation of a Distributed Home Automation System(Sciencedirect, 2016-01-01) Otuoze, Abdulrahaman; Abdulrahman, TA; NT, Surajudeen-Bakinde; Isiwekpeni, OHThis work presents the design and model implementation of a novel home automation system applying the Internet of Things (IoT) technology. It seeks simplified design protocols for developing a robust home automation system to deal with the problems of complexity, multiple incompatible standards and the resulting expenses in the existing systems. The embedded system features the ubiquitous low-cost 32-bit ESP8266 System-on-chip (SoC) module interfaced to some sensors and actuators for interaction in the home. Flexibility in the remote access, operation and management is achieved through HTML5 based intuitive mobile and web GUI applications. Web Application Messaging Protocol (WAMP) is deployed to ensure that individual applications and systems seamlessly communicate with a relatively high level of security using robust web service security protocol. This system offers a cost-effective and efficient solution, because the costs of a dedicated public IP address and a high-end computer are excluded, which are present mostly in other solutions.Item Implementation of a Cloud-Based Home Automation System(CPJ, 2016) Otuoze, Abdulrahaman; NT, Surajudeen-Bakinde; Isiwekpeni, OH; Abdulrahman, TAHome automations provide full control and flexible monitoring of home appliances for increased comfort, efficient energy use, costs saving, improved safety and security, and have driven the development of various smart homes technologies. This paper presents the implementation of a home automation system utilizing the Internet of Things (IoT) technology. This work tackles the problems of complexity and incompatible standards inherent in the existing home automation solutions using a robust distributed computing approach. The embedded system operates on dual Advanced Virtual RISC (AVR) microcontrollers, ATmega328p and ATmega16L, interfaced to input and output modules – sensors, actuators, Wi-Fi shield, LCD, keypad etc. – for interactions with users, appliances and the environment. The HTML5 based intuitive mobile and web applications, developed for the system, induces unrestricted flexibility in the system operations and management. The system deploys a novel Web Application Messaging Protocol (WAMP), implemented with WebSocket full duplex and persistent connection protocol and JSON data serialization, for seamless individual applications and subsystems integration with a relatively high level of security through web service security protocol. This cloud-based home automation solution has lower implementation cost compared to the existent systems because, as it removes the expensive costs of on-premise high end computers and dedicated public IP addresses.
