Smart Grid is a large complex system, involving generation, transmission, distribution and delivery of four links. This paper analyzes the structure of the smart grid system in depth with a combination of qualitative and quantitative research approach. Then it explains state variables, rate variables and constants in the development of smart grid system under the Vensim software environment and...

An appealing feature of blockchain technology is smart contracts. A smart contract is executable code that runs on top of the blockchain to facilitate, execute and enforce an agreement between untrusted parties without the involvement of a trusted third party. In this paper, we conduct a systematic mapping study to collect all research that is relevant to smart contracts from a technical perspe...

T o be effective, smart systems need to be instrumented, interconnected, and intelligent. Instrumentation enables the collection of timely, high-quality data through embedded sensors that communicate over wireless or wired networks. Instrumented devices such as smart meters for gas, electricity, and water continually monitor the supply and demand for these utilities, and might actuate strategie...

Purpose – Smart spaces are open complex computing systems, consisting of a large variety of cooperative smart things. Central to building smart spaces is the support for sophisticated coordination among diverse smart things collaborating to accomplish specified tasks. Multi-agent systems are often used as the software infrastructures to address the coordination issue in smart spaces. However, s...

Lifecycle management enables enterprises to manage their products, services and product-service bundles. IoT and CPS have made products and services smarter by closing the loop of data across different phases of lifecycle. Similarly, CPS and IoT empower cities with real-time data streams from heterogeneous objects. Yet, cities are smarter and more powerful when relevant data can be exchanged be...

In recent years more and more security sensitive applications use passive smart devices such as contactless smart cards and RFID tags. Cost constraints imply a small hardware footprint of all components of a smart device. One particular problem of all passive smart devices such as RFID tags and contactless smart cards are the harsh power constraints. On the other hand, active smart devices have...

Urbanization grows steadily, i.e. more humans live at one place and rural areas are more unpopular. Urbanization faces challenges for city planning and development. Cities have to deal with large crowds, high energy consumption, large quantities of garbage etc. Thus, smart cities have to meet many requirements of different areas. Hence, realizing smart cities can be supported by linking differe...

This paper introduces a novel way to allow non-expert users to create smart surroundings. Non-smart everyday objects such as furniture and appliances found in homes and offices can be converted to smart ones by attaching computers, sensors, and devices. In this way, non-smart components that form non-smart objects are made smart in advance. For our first prototype, we have developed u-Texture, ...

Intelligent information systems are necessary to improve power grid operations. The current trend reveals the deployment of smart meter at consumer sites as the energy provider’s starting point to grid modernisation. Smart meters are considered as a core element in most of the smart grid projects. The smart metering system is designed to collect and transmit detailed consumption data. Detailed ...
