Examining the Concept of Smart Home Technologies (IoT Systems)

With the huge advancement in wireless sensor networks and other computer technologies, Home automation plays an important role in human life by making Lives at home easier and faster. Over the years, several smart home systems have been developed using network wireless systems such as Controller Area Network(CAN), Wi-Fi, Bluetooth, Radio Frequency, Cognitive radio, and several others. With this technology, the user easily controls their homes through their computer and assigns actions dependent on time or sensor readings if any from the device in the network of the home automation irrespective of the location of the user. This technology isn’t only limited to controlling appliances around us remotely but also helps in terms of security by warning the user during unusual and critical situations. Home automation is flexibly used in different places with high precision which saves time and money, and also provides comfort, security, and convenience to its user. Home automation can also help the aged and incapacitated people and provide quality of life to people without the need for caregivers or any care from institutions. People's desire for an intelligent home has increased dramatically in recent years as mobile connectivity devices are much more convenient and simple. This paper focuses on several smart home systems that have been developed in the twentieth century. Networks are enhanced by IoT to collect and analyze data proficiently from sensors and actuators. IoT creating a new era in the world of information and technologies in the areas of security has become vital as intrusion, theft, fire, and leakage of flammable gas that are threats to human lives never fails to continuously be a threat to humanity. IoT is the existing network of the internet where the computer systems will connect to real-world objects or things such as vehicles, devices, home appliances, and many others. This technology saves human energy and it is also a user-friendly safe system that makes the life of its user easier. Keywords: Smart Home, IoT, sensors, home automation ,Controller Area Network.

A Review on Energy Consumption Optimization Techniques in IoT Based Smart Building Environments

In recent years, due to the unnecessary wastage of electrical energy in residential buildings, the requirement of energy optimization and user comfort has gained vital importance. In the literature, various techniques have been proposed addressing the energy optimization problem. The goal of each technique was to maintain a balance between user comfort and energy requirements such that the user can achieve the desired comfort level with the minimum amount of energy consumption. Researchers have addressed the issue with the help of different optimization algorithms and variations in the parameters to reduce energy consumption. To the best of our knowledge, this problem is not solved yet due to its challenging nature. The gap in the literature is due to the advancements in the technology and drawbacks of the optimization algorithms and the introduction of different new optimization algorithms. Further, many newly proposed optimization algorithms which have produced better accuracy on the benchmark instances but have not been applied yet for the optimization of energy consumption in smart homes. In this paper, we have carried out a detailed literature review of the techniques used for the optimization of energy consumption and scheduling in smart homes. The detailed discussion has been carried out on different factors contributing towards thermal comfort, visual comfort, and air quality comfort. We have also reviewed the fog and edge computing techniques used in smart homes

System Design of Internet-of-Things for Residential Smart Grid

Internet-of-Things (IoTs) envisions to integrate, coordinate, communicate, and collaborate real-world objects in order to perform daily tasks in a more intelligent and efficient manner. To comprehend this vision, this paper studies the design of a large scale IoT system for smart grid application, which constitutes a large number of home users and has the requirement of fast response time. In particular, we focus on the messaging protocol of a universal IoT home gateway, where our cloud enabled system consists of a backend server, unified home gateway (UHG) at the end users, and user interface for mobile devices. We discuss the features of such IoT system to support a large scale deployment with a UHG and real-time residential smart grid applications. Based on the requirements, we design an IoT system using the XMPP protocol, and implemented in a testbed for energy management applications. To show the effectiveness of the designed testbed, we present some results using the proposed IoT architecture.Comment: 10 pages, 6 figures, journal pape

Smart home energy management

The new challenges on Information and Communication Technologies (ICT) in Automatic Home Systems (AHS) focus on the methods useful to monitor, control, and optimize the data management flow and the use of energy. An AHS is a residential dwelling, in some cases with a garden or an outdoor space, equipped with sensors and actuators to collect data and send controls according to the activities and expectations of the occupants/users. Home automation provides a centralized or distributed control of electrical appliances. Adding intelligence to the home environment, it would be possible to obtain, not only excellent levels of comfort, but also energy savings both inside and outside the dwelling, for instance using smart solutions for the management of the external lights and of the garden
