Home Automation and power saving Research Papers (original) (raw)

As in today's date fuel consumption is important in everything from scooters to oil tankers, power consumption is a key parameter in most electronics applications. The most obvious applications for which power consumption is critical are battery-powered applications, such as home thermostats and security systems, in which the battery must last for years. Low power also leads to smaller power supplies, less expensive batteries, and enables products to be powered by signal lines (such as fire alarm wires) lowering the cost of the end-product. As a result, low power consumption has become a key parameter of microcontroller designs. The purpose of this paper is to summarize, mainly by way of examples,what in our experience are the most trustful approaches to lowpower design. In other words, our contribution should not be intended as an exhaustive survey of the existing literature on low-power esign; rather, we would like to provide insights a designer can rely upon when power consumption is a critical constraint.We will focus on the reduction of power consumption on different technologies for different values of oicapacitance and also compare power saving in technologies.

The fast development in computer and various mobile devices have bought changes to our living environment. Pressing a button to open the door of flat when we are in office is no longer purely imagination in cartoons or films. More importantly, home automation as such provides us an alternative solution to reduce the usage of energy, save costs and conven-ience. This paper reviews the advantages of home automation smart home in Hong Kong and Australia from industry perspective with the help of content analysis.

This paper presents the overall design of Home automation system with low cost and wireless system. Home automation plays an important role in our daily life. Home automation saves money, time and it also reduces labour work. Home automation system is advantageous for old aged and handicapped person. The standard of living at home is also improved by smart home concept. The switch mode and voice mode are used to control the home appliances. The video feedback is received in the android application which streams the video of IP Camera. This paper presents the main control system which implements the wireless technology and this technology provides remote access from android phones. The design remains the existing electrical switches and provides more safety control on the switches with low voltage activating method. The switches status is synchronized in all the control system whereby every user interface decodes the real time existing switches status. This system is designed to control electrical appliances and devices in house with low cost and ease of installation. The system designed in this paper is user friendly.

The Internet of Things (IoT) is the most recent technology platform. We may regulate our daily routine work, such as home applications, control, and simple communication systems, using IOT, and improve our digital services. The Internet of Things (IoT) is a system that intelligently adds everyday content information to the internet in order to facilitate communication between objects and humans, as well as among themselves. In this study, we demonstrate how IoT can improve home automation. The relay, Node MCU, which is a network access component, is used in our suggested system. We can control that equipment using an IoT-based system technique. Mobile phones, computers, and tablets are used as user interfaces in home automation systems. They can connect to the home automation network through a wireless internet connection. The user will interact with the system directly via the control interface, while home appliances will be controlled remotely via a mobile app. An additional aspect of the home automation system is that it may be protected remotely. This redesigned design concept provided a home automation system that could be controlled efficiently.

This paper presents a GSM based electronic appliances monitoring and controlling system. This enables individuals to connect their home or office electronic appliances to the developed system which in turn enables them to remotely monitor and control these appliances though a Short Message Service (SMS). In remotely controlling the connected electronic appliances, users can determine the status of the electronic appliances remotely and decide whether to either switch any of the connected electronic appliances on or off. The uniqueness of the approach introduced is further revealed in the way the GSM module of the developed system was integrated with the PIC16F877Amicrocontroller to give a single and more compact system. Also, the SMS format used in monitoring and controlling the connected electronic appliances allows users to control their electronic appliances from anywhere provided there is a GSM network; hence, distance was not a barrier. The SMS format used is not lengthy and is simple to understand which makes it attractive to its users. The performance of the developed system was evaluated by connecting twelve (12) electronic appliances with it and the developed system shows the capability to remotely monitor and control them.

Modern Smart Environments (SmE) are equipped with a multitude of devices and sensors aimed at intelligent services. The
variety of devices has raised a major problem of managing SmE. An increasingly adopted solution to the problem is the modeling
of goals and intentions, and then using artificial intelligence to control the respective SmE accordingly. Generally, the solution
advocates that the goals can be achieved by controlling the evolution of the states of the devices. In order to automatically reach
a particular state, a sophisticated solution is required through which the respective commands, notifications and their correct
sequence can be discovered and enforced on the real devices.
In this paper, a comprehensive methodology is proposed by considering a) the composite nature of the state of an individual
device; b) the possible variation of specific commands, notifications and their sequence based on the current states of the devices.
The methodology works at two levels: design-time and runtime. At design-time, it constructs the extended data and control flow
behavioral graphs of the devices by using the concepts of a model checking approach. Then, at runtime, it uses these graphs for
finding the reliable evolution through which the desired goal can be fulfilled. The proposed methodology is implemented over
the Domotic Effects framework and a home automation system, i.e. Domotic OSGi Gateway (Dog). The implementation and
experimentation details indicate the effectiveness of the proposed approach.

While the semiconductor roadmap is about to locate in 16nm-FinFET (or Tri-Gate) era, power budget is
being entitled major concern to contemporary electronics and future nanometer devices. In this work, a
new Power Distribution Network (PDN), referred to as HiPDN, is disclosed for further fine-grain power
saving and higher power integrity for supplies in multi-voltage domains. The proposed PDN employs two
types of Integrated Voltage Regulators (IVR) with large difference in voltage regulation range. By
combining the proposed PDN with the Adaptive Voltage Scaling (AVS) technique, voltage guard-bands can
be mitigated to lower the safety margin for voltage variation, i.e., reducing DC set points, thereby
effectively decreasing the overhead of power dissipation. In comparison to existing PDNs, theoretical
results with a simple equivalent circuit model demonstrate an increase of power saving achieved by
HiPDN, thus, allowing longer battery life. Finally, this work provides an on-chip power delivery
methodology to improve power efficiency and a simple model to evaluate a PDN and its IVRs.
