The paper discusses Home Area Networks (HAN) communication technologies for smart home and domestic application integration. The work is initiated by identifying the application areas that can benefit from this integration. A broad and inclusive home communication interface is analysed utilizing as a key piece a Gateway based on machine-to-machine (M2M) communications that interacts with the surrounding environment. Then, the main wireless networks are thoroughly assessed, and later, their suitability to the requirements of HAN considering the application area is analysed. Finally, a qualitative analysis is portrayed.

This paper presents a solar water heating system with novel safety and energy management functions that protect both the solar installation and users health. The planned system schedules safeguarding operations and improves the efficiency of the heat transfer mechanism. The system prevents Legionella pneumophila bacteria colonies outbreaks and promotes energy management by using an extensive set of data, retrieved from strategically located probes that properly feed the implemented control algorithms. The methodology and the reported technical solutions in this research could be, in the future, used as an integrated part of the smart grid home area network being nowadays, in its simplest form, a practical guide to promote mass market usage of the solar water heating systems in Portugal.

Home Area Network (HAN) forms an integral part of the Smart Grid technology providing a smarter Solution to the energy crisis. This article proposes a remote interface controller for Smart Homes as a part of Home Automation and Demand Side Management. The intelligent controller submits the user with the individual energy consumption profiles of the appliances at his home on an android mobile application providing the user with dual appliance control (on/off) options: manual or automatic. The former requires manual control of the appliances while the latter lets the controller make the decision based on dynamic tariff rates using Fuzzy Logic. This system being user friendly can be adopted for the Smart Grid and Smarter homes.

Strengthening of Smart Grid functionalities has become the need of the 21st Century. Security evolves to be the primary concern at the deployment level of Smart Grids. Cyber security threats and vulnerabilities in Smart grid Network needs to be addressed before the deployment of the Smart Grid. Our proposed intrusion detection scheme identifies anomalies in the Smart Grid traffic and detects attacks like flooding which causes Denial of Service in Smart Grid Networks. This paper applies k-Means algorithm for clustering of traffic data and outlier detection for the data transmitted between utility Centre and the Smart Homes. Performance of the algorithm has been compared with other clustering algorithms and the results were found to have higher percentage in anomaly detection.

Residential thermostats control a substantial portion of both fuel and electrical energy—9% of the total energy consumption in the U.S. Consumers install programmable thermostats to save energy, yet numerous recent studies found that homes with programmable thermostats can use more energy than those controlled manually depending on how—or if—they are used. At the same time, thermostats are undergoing a dramatic increase in capability and features, including control of ventilation, responding to electricity price signals, and interacting with a home area network. These issues warrant a review of the current state of thermostats, evaluating their effectiveness in providing thermal comfort and energy savings, and identifying areas for further improvement or research. This review covers the evolution in technologies of residential thermostats; we found few standards and many features. We discuss studies of how people currently use thermostats, finding that nearly half do not use the programming features. The review covers the complications associated with using a thermostat. Finally, we suggest research needed to design—and especially test with users—thermostats that can provide more comfortable and economical indoor environments.

High-speed power line communication (PLC) is useful technology to easily build the communication networks, because construction of new infrastructure is not necessary. In Europe and America, PLC has been used for broadband networks since the beginning of 21th century. In Japan, high-speed PLC was deregulated only indoor usage in 2006. Afterward it has been widely used for home area network, LAN in hotels and school buildings and so on. And recently, PLC is greatly concerned as communication technology for smart grid network. In this paper, the author surveys the high-speed PLC technology and its current status.

This paper analyzes a consumption scheduling mechanism for domestic appliances within a home area network. The aim of the proposed scheduling is to minimize the total energy price paid by the consumer and to reduce power peaks in order to achieve a balanced daily load schedule. An exact and computationally efficient mixed-integer linear programming (MILP) formulation of the problem is presented. This model is verified by several problem instances. Realistic scenarios based on the real price tariffs commercially available in the Czech Republic are calculated. The results obtained by solving the optimization problem are compared with a simulation of the ripple control service currently used by many domestic consumers in the Czech Republic Článek se věnuje návrhu a ověření algoritmu pro optimalizaci běhu domácích spotřebičů z hlediska úspory nákladů na jejich provoz.

Model je v článku ověřen na několika realistických scénářích vycházejících z podmínek na domácím energetickém trhu.

Electronic equipment for detecting or compensating power quality disturbances in domestic appliances need fast and reliable voltage sag or swell detection algorithms. There are commonly used methods to detect voltage events, but the most popular is the measurement of the RMS value of voltage. Even this method has well-known associate drawbacks, a step forward in this way is presented in this paper: a fast, low cost and high efficiency RMS meter that uses a minimum algorithm for calculating the voltage RMS value in a single phase supply line that can be embedded in a home area network device. The proposed system has been designed, implemented and tested and experimental results are shown to illustrate its functionality.

Smart Energy Home Area Networks (SE-HAN) enable two-way communication between utility companies and HAN devices. Due to multifaceted nature of SE-HAN, securely managing SE-HAN is very challenging. In this paper, we propose a device authentication mechanism for smart energy home area network. The proposed mechanism is more robust and secure than the existing one.

A miniature wireless node for ECG measurements is presented. The ECG node is designed to be used in various applications including measurement of heart rate during physical exercise and continuous long term measurement of ECG for people assumed having, or being recovering from a cardiac disease. The ECG node is wirelessly connected to a computer using IEEE 802.15.4 based radio protocol. The device sends the measured ECG signal together with additional measurement parameters including battery voltage to the computer, where the ECG signal can be analyzed on-line. The ECG node can operate alone or it can be used as a part of an overall system being designed for monitoring people that are transferred from hospital to home treatment.

Our first speaker is known throughout the industry as the Father of the Minicomputer, although I’m sure he has mixed feelings about this. And I guess he is the embodiment of the saying, “You only know where you’re going if you know where you’ve been.” He’s been a very significant part of the industry since the very early days, so when he talks about the matter of predicting, his views are grounded in considerable experience of doing just that in his 23 years, for instance, as vice president of R & D at Digital Equipment Corporation. He was educated at MIT. From 1966 to 1972, he was professor of Computer Science and Engineering at Carnegie Mellon, and from 1986 to 1987 was the first assistant director of the National Science Foundation Computing Directorate. He led the National Research Network Panel that became the NIIGII and authored the first high-performance computer-and-communications initiative.

The cost of asynchronous transfer mode technology is falling while its deployment is growing. Once regarded as a technology strictly for rates above 100 Mbps, ATM may now be considered for any networking scenario where multimedia and real-time are important. We look at a possible deployment path for ATM technology in the home and explain some of our practical work. These are both based on dumb ATM devices which can be built for low cost. The style of operation and method of control of these dumb devices uses the approach of the ATM Warren. The Warren is a method of building low cost ATM devices and switches where the cost savings are achieved by using fixed VCI values in end stations and by using proxy control from a single processor, rather than local control processors in each device or switch.

With increasing oil price and environment pollution, especially in large cities, electric vehicles are getting to be more interesting than they were several years ago. Using electric vehicles in cities and large agglomerations lead to less pollution caused by common cars combustion engines (nitrogen oxides, carbon oxides, dust particles). Electric vehicles are more considerate to the environment than traditional cars even when the energy produced by non-renewable energy resources is used for their charging. The lack of the infrastructure prevents electric vehicles spreading. This paper describes standards and ideas how to integrate electric vehicle charger to the home area network. Home area network is a local part of SmartGrid network usually situated in homes. All devices connected to this network should implement several specifications. Basic requirements to charger properties are summarized.
