Asymmetric Information Issues and Solutions for the Broker Executing SLA-based Workflows

In the business Grid environment, the user should ask the broker to execute the workflow for him and then pays the broker for the workflow execution service. As the sub-jobs of the workflow must be distributed over many Grid resource providers to ensure the QoS, the broker knows about all aspects of all service providers while it is difficult for user to have this information. Thus, there is an asymmetric information situation. The asymmetric information may bring a negative effect to the broker. This paper will analyze the asymmetric information issues and propose possible solutions to solve the problem

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
