Development of an IoT Based Shopping Trolley

The modern technology has augmented the quality of living for the humans. There has been an emerging demand for fast and straightforward payment of bills in supermarkets. People crave for a high quality with modern technology in everything we tend to use in our daily lives. This project describes the way to build an automatic and time saving system for the globe of retail which can build shopping experience impetuous, client friendly and secure. In the reality, shopping at super markets, malls has resulted in massive crowds to long lines at the billing counter as a result of the cashier has got to scan each product item then enter it into the billing record. The existing billing system may be a bit time overwhelming and that’s where the thought of IoT based Automated Shopping Trolley –a remedial electronic product to catch-up with this downside emerged. This is supported by Raspberry Pi fitted with a LED screen and QR scanner and a wireless technology referred to as Bluetooth. The digital display(LED) used may be a 16x2 and Bluetooth modules build the wireless network to figure simply between a particular ranges. A unique product with social acceptance is that the one that aids the comfort, convenience and potency in standard of living. The temporary description of its operation is, after you choose a product and drop it into the trolley, the QR scanner scans the product’s distinctive code and its worth.. Card payment facility is also made available below the LCD display. If payment is via cash then he/she has to visit the counter and pay the bill as displayed on the LCD screen fit. This will save the time that was earlier being consumed to scan each item. The entire system will work on RFID tags. The entire database and product info is stored using Cloud Technology. Anti-theft protection is enabled. Indoor Navigation facility is also enabled

Intelligent wireless web services: context-aware computing in construction-logistics supply chain

The construction industry has incurred a considerable amount of waste as a result of poor logistics supply chain network management. Therefore, managing logistics in the construction industry is critical. An effective logistic system ensures delivery of the right products and services to the right players at the right time while minimising costs and rewarding all sectors based on value added to the supply chain. This paper reports on an on-going research study on the concept of context-aware services delivery in the construction project supply chain logistics. As part of the emerging wireless technologies, an Intelligent Wireless Web (IWW) using context-aware computing capability represents the next generation ICT application to construction-logistics management. This intelligent system has the potential of serving and improving the construction logistics through access to context-specific data, information and services. Existing mobile communication deployments in the construction industry rely on static modes of information delivery and do not take into account the worker’s changing context and dynamic project conditions. The major problems in these applications are lack of context-specificity in the distribution of information, services and other project resources, and lack of cohesion with the existing desktop based ICT infrastructure. The research works focus on identifying the context dimension such as user context, environmental context and project context, selection of technologies to capture context-parameters such wireless sensors and RFID, selection of supporting technologies such as wireless communication, Semantic Web, Web Services, agents, etc. The process of integration of Context-Aware Computing and Web-Services to facilitate the creation of intelligent collaboration environment for managing construction logistics will take into account all the necessary critical parameters such as storage, transportation, distribution, assembly, etc. within off and on-site project

State of the Art, Trends and Future of Bluetooth Low Energy, Near Field Communication and Visible Light Communication in the Development of Smart Cities

The current social impact of new technologies has produced major changes in all areas of society, creating the concept of a smart city supported by an electronic infrastructure, telecommunications and information technology. This paper presents a review of Bluetooth Low Energy (BLE), Near Field Communication (NFC) and Visible Light Communication (VLC) and their use and influence within different areas of the development of the smart city. The document also presents a review of Big Data Solutions for the management of information and the extraction of knowledge in an environment where things are connected by an “Internet of Things” (IoT) network. Lastly, we present how these technologies can be combined together to benefit the development of the smart city
