A suitable system to control the energy usage is one of the solutions for this crisis. Load shedding, power cut etc. helps to rearrange the available power but they can't be used to prevent the unwanted usage of energy, peak time load control etc. Also a system is needed to monitor the power consumption of an overall area to select the areas to suitably control the energy usage. One of the easiest solutions for this is by using power line communication. PLC is the communication technology that enables sending data over existing power cables. This means that with just power cables running to an electrical device, one can power it up and at the same time control/retrieve data from the device in full duplex manner. The major advantage of PLC is that it does not need extra cables. It uses existing wires. Thus by using power line communication we can monitor and control the usage of devices by providing a control the usage of devices by providing a control circuit at consumer end.

Received: 18 August 2019; Accepted: 19 September 2019; Published: 26 September 2019 Abstract: Smart cities require interactive management of water supply networks and water meters play an important role in such a task. As compared to fully mechanical water meters, electromechanical water meters or fully electronic water meters can collect real-time information through automatic meter reading (AMR), which makes them more suitable for smart cities applications. In this paper, we first study the design principles of existing water meters, and then present our design and implementation of a self-powered smart water meter. The proposed water meter is based on a water turbine generator, which serves for two purposes: (i) to sense the water flow through adaptive signal processing performed on the generated voltage; and (ii) to produce electricity to charge batteries for the smart meter to function properly. In particular, we present the design considerations and implementation details. The wireless transceiver is integrated in the proposed water meter so that it can provide real-time water flow information. In addition, a mobile phone application is designed to provide a user with a convenient tool for water usage monitoring.

Most countries started to convert their existing cities into smart cities or construct new smart cities in order to improve the quality of life of their inhabitants. However, the problem that facing those countries while applying the concept of smart cities is the costs, especially for the residential sector. Despite the high initial and even operation costs for adopting different technologies in smart housing; the benefits could exceed those costs within the lifespan of the project. This article is shedding the light on the economics of smart housing. This study aims to evaluate the net present value (NPV) of a smart economic housing model to check the viability and feasibility of such projects. The calculation of the NPV based on Monte Carlo simulation provides an interesting methodological framework to evaluate the robustness of the results as well as providing a simple way to test for statistical significance of the results. This analysis helps to evaluate the potential profitability of smart housing solutions.

    AUTOMATIC METER READING Dan Kritz Itron, Inc. 2818 N. Sullivan Rd. Spokane Valley, Washington 99216 Abstract Automated meter reading (AMR) is the collection at a remote central location of data from meters and other devices at customers’ premises via telecommunications. The AMR industry has grown steadily over the past 30 years. Today, a few established players dominate the natural gas AMR sector, with many other smaller companies competing for sales as well. Technological, regulatory, and economic trends are driving the further evolution and adoption of AMR solutions. Birth of AMR Technology companies wax nostalgic over their humble origins, such as Hewlett-Packard and their red barn or Apple Computer and Steve Jobs’ garage. In the AMR industry, Itron looks back to December 1977 and the rented space behind Gator McCluskie’s Bar in Hauser Lake, Idaho. Two days after moving into their new offices, Itron received initial funding from Washington Water Power, today known as Avista Utilities. The Datameter was the first successful AMR device. By November 1978, WWP was field testing the first Itron portable computer to automate meter reading. It was Current state of gas AMR and utility AMR in general named the Datameter and allowed utility meter readers to Today, more than 80 million meters worldwide are read generate a bill on the spot once a meter reading was automatically, with nearly three-quarters of those in the entered. The Datameter stored route information and United States. In the U.S. alone, more than 17 million meter readings on cassette tapes. WWP hoped it would natural gas meters are read automatically.
