College of Engineering & Management Studies & Research, Kopri, Thane (E), Maharashtra, India Abstract— Voice Controlled Home Automation is a very useful project for the adults and physically disabled persons, who are not able to do various activities efficiently when they are at home and need one’s assistant to perform those tasks. With the Voice Recognition the complication of wiring in case of wired automation is prevented. With the use of Bluetooth Home Automation considerable amount of power saving is possible and it is flexible and compatible with future technologies so it can be easily customized for individual requirements. Voice recognition system provides secure access to home. In the recent years, the Home Automation systems have seen rapid changes due to introduction of various wireless technologies. Home Automation industry is growing rapidly, this is fuelled by the need to provide supporting systems that are made to ease our life. Automation systems is supposed to be implemented in existing home environments, without any changes in the infrastructure. The automation is based on recognition of voice commands and uses Bluetooth modules along with microcontroller. This paper presents the overall design of ‘Voice Controlled Home Automation’, which we are currently developing.

Design and Implementation of Internet of Things for Home Environment A thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Electronics and Computer Systems Engineering at Massey University, Manawatu, New Zealand. Sean Kelly 2013 Abstract An integrated framework for smart home monitoring towards internet of things based on ZigBee and 6LoWPAN wireless sensor networks is presented. The system was developed to retrofit existing sub systems of wireless technologies in order to reduce cost, and complexity. The practical internetworking architecture and the connection procedures for reliable measurement of smart sensors parameters and transmission of sensing data via internet are presented. A ZigBee based sensing system was designed and developed to see the feasibility of the system in home automation for contextual environmental monitoring. The ubiquitous sensing system is based on combination of pervasive distributed sensing units and an information system for data aggregation and analysis. Results related to the home automation parameters and execution of the system running continuously for long durations is encouraging. The prototype system (ZigBee based) was tested to generate real-time graphical information rather than using a simulator or a test bed scenario. A trail has also been performed with 6LoWPAN technology to provide functionality as the ZigBee based system. The overall internetworking architecture describes the integration of a low power consumption wireless sensor network with the internet.

  • Wolfbot: a Distributed Mobile Sensing Platform for Research and Education
    Proceedings of 2014 Zone 1 Conference of the American Society for Engineering Education (ASEE Zone 1) WolfBot: A Distributed Mobile Sensing Platform for Research and Education Joseph Betthauser, Daniel Benavides, Jeff Schornick, Neal O’Hara, Jimit Patel, Jeremy Cole, Edgar Lobaton Abstract— Mobile sensor networks are often composed of agents with weak processing capabilities and some means of mobility. However, recent developments in embedded systems have enabled more powerful and portable processing units capable of analyzing complex data streams in real time. Systems with such capabilities are able to perform tasks such as 3D visual localization and tracking of targets. They are also well-suited for environmental monitoring using a combination of cameras, microphones, and sensors for temperature, air-quality, and pressure. Still there are few compact platforms that combine state of the art hardware with accessible software, an open source design, and an affordable price. In this paper, we present an in- depth comparison of several mobile distributed sensor network platforms, and we introduce the WolfBot platform which offers a balance between capabilities, accessibility, cost and an open- design. Experiments analyzing its computer-vision capabilities, power consumption, and system integration are provided. Index Terms— Distributed sensing platform, Swarm robotics, Open design platform. I.

  • Long-Range Wireless Radio Technologies: a Survey
    future internet Review Long-Range Wireless Radio Technologies: A Survey Brandon Foubert * and Nathalie Mitton Inria Lille - Nord Europe, 59650 Villeneuve d’Ascq, France; [email protected] * Correspondence: [email protected] Received: 19 December 2019; Accepted: 11 January 2020; Published: 14 January 2020 Abstract: Wireless networks are now a part of the everyday life of many people and are used for many applications. Recently, new technologies that enable low-power and long-range communications have emerged. These technologies, in opposition to more traditional communication technologies rather defined as "short range", allow kilometer-wide wireless communications. Long-range technologies are used to form Low-Power Wide-Area Networks (LPWAN). Many LPWAN technologies are available, and they offer different performances, business models etc., answering different applications’ needs. This makes it hard to find the right tool for a specific use case. In this article, we present a survey about the long-range technologies available presently as well as the technical characteristics they offer. Then we propose a discussion about the energy consumption of each alternative and which one may be most adapted depending on the use case requirements and expectations, as well as guidelines to choose the best suited technology. Keywords: long-range; wireless; IoT; LPWAN; mobile; cellular; LoRa; Sigfox; LTE-M; NB-IoT 1. Introduction Wireless radio technologies, such as Wi-Fi, are used daily to enable inter-device communications. In the last few years, new kinds of wireless technologies have emerged. In opposition to standard wireless technologies referred to as “short-range”, long-range radio technologies allow devices to communicate over kilometers-wide distances at a low energy cost, but at the expense of a low data rate.

The field of approach to Zigbee Based Wireless Network for Industrial Applications has been standardized now a days. A wireless control and monitoring system for a industrial machines realized using the Zigbee communication protocol for safe and economic data communication in industrial fields where the wired communication is either more expensive or impossible due to physical conditions. The machines can be controlled wireless due to the microcontroller interface developed with Zigbee. It is also possible to protect the machines against some critical conditions such as change in temperature, humidity, light, pressure etc. so controlling, monitoring, and protection of the system are realized in real time. So the wireless communication technology is used in this paper, controlling abilities of the system are increased and also hardware and the necessities of other similar equipment for data communication are minimized. We concerns with designing and implementing the system which can be utilized effectively to reduce human efforts and accuracy of measurement of data. The main work behind this is to make instrumentation system more power full by enabling it modern communication technologies. Here we are using different sensors like temperature and humidity to measure surrounding temperature and humidity.

To track the locations of the vehicles in the designed WSN infrastructure, a GTPA010 GPS module was used at the end devices components placed on vehicles. Moreover, the XBee S1 modules based on the ZigBee protocol were used to wirelessly transmit the obtained location data to a center node. An ASP.Net-based web application has been developed to graphically present the vehicle location information in a security center and record them in the MSSQL database at intervals of 5 minutes. It also notifies system administrators in case of long waiting times of the vehicles in the areas outside the pre-specified areas.
