New technological advancements allow the Internet to penetrate in embedded computing. IPv6 envisions to merge the physical and the digital world, through the Internet. The Web of Things interconnects the expanding ecosystem of Internet-enabled embedded devices, by reusing well-accepted and understood Web principles. In this talk, we will present the development of a Web-based application framework for smart homes, supporting concurrent interaction from multiple family members. By employing intermediate request queues, associated with the physical devices of the smart home, our analysis shows that we can mask transmission failures and faults that occur in the wireless environment, thus enhancing the performance of smart home operations by means of fast retransmissions, load balancing and request priority techniques. In our analysis, we also derive formulas for estimating the response time of requests and for setting the request queue retransmission interval, an important design parameter of the system. In this way, reliability and timely responses from the devices are ensured. We demonstrate that, by using the Web as application layer, flexible applications for smart homes can be built, on top of heterogeneous embedded devices, with little effort. We address many issues related to Web-enabling household devices, from their local discovery and service description to the uniform interaction with them. Our technical evaluation indicates that the process of Web-enabling physical devices offers satisfactory performance, mainly in terms of response time and energy consumption, while modern Web techniques such as Web caching and event-based Web messaging can contribute in facilitating smart home operations. Through various case studies, we demonstrate that Web-based, energy-aware smart homes have the potential to provide flexible solutions to challenges such as energy awareness and conservation, and be smoothly integrated with the smart grid of electricity. Finally, this talk discusses some future research challenges, beyond the home environment, in which Web-based smart homes may constitute crucial elements in order to address them effectively.
Andreas Kamilaris received the BSc degree in Computer Science from University of Cyprus in 2007 and the MS degree in Distributed Systems from the ETH University of Zurich, Switzerland in 2009. He is a PhD student at the Computer Science department of the University of Cyprus, under the supervision of Prof. Andreas Pitsillides, collaborating with the Institute for Pervasive Computing of the ETH Zurich, in the research area of the Web of Things. His research interests involve ad hoc, wireless sensor networks, the Internet/Web of Things, smart metering and energy awareness, ubiquitous computing, smart homes and home automation, and Web technologies.
