A test-bed for the Correlation Center of Digital Services

For an e-business to be successful, companies need to formulate a business strategy, have informative strategic alliances, develop an international system, build a proactive infrastructure, internationalize their model, capture the residual value, exploit the international telecommunications liberalization, homogenize the data structure and globalize human resources. To achieve their objective, businesses need a more integrated automation system to speed up the process of establishing and conducting Internet-based services. In this paper, a component-based prototyping approach is used in developing a generic model and framework for a correlation center that provides entrepreneurs with a tool to quickly build and automate e-commerce linkages, thus enabling companies to establish their businesses over the Internet using a proven methodology

Hybrid-Vehfog: A Robust Approach for Reliable Dissemination of Critical Messages in Connected Vehicles

Vehicular Ad-hoc Networks (VANET) enable efficient communication between vehicles with the aim of improving road safety. However, the growing number of vehicles in dense regions and obstacle shadowing regions like Manhattan and other downtown areas leads to frequent disconnection problems resulting in disrupted radio wave propagation between vehicles. To address this issue and to transmit critical messages between vehicles and drones deployed from service vehicles to overcome road incidents and obstacles, we proposed a hybrid technique based on fog computing called Hybrid-Vehfog to disseminate messages in obstacle shadowing regions, and multi-hop technique to disseminate messages in non-obstacle shadowing regions. Our proposed algorithm dynamically adapts to changes in an environment and benefits in efficiency with robust drone deployment capability as needed. Performance of Hybrid-Vehfog is carried out in Network Simulator (NS-2) and Simulation of Urban Mobility (SUMO) simulators. The results showed that Hybrid-Vehfog outperformed Cloud-assisted Message Downlink Dissemination Scheme (CMDS), Cross-Layer Broadcast Protocol (CLBP), PEer-to-Peer protocol for Allocated REsource (PrEPARE), Fog-Named Data Networking (NDN) with mobility, and flooding schemes at all vehicle densities and simulation times

Systematic Component-Oriented Development with Axiomatic Design

A form of design guidance is offered through a process that applies Axiomatic Design Theory to Component-Orientation. Axiomatic Design has been proposed by Do and Suh for object-oriented software development. Our approach leverages divide-and-conquer and find-integrate techniques that support service-based development as an alternative to developing code from scratch. Using this process, missing or conflicting components can be identified, and missing components can be defined. The effectiveness of our proposed system is demonstrated through an example based on High Level Architecture (HLA) simulations. Our Component-Oriented approach utilizing axiomatic design theory has been adapted to HLA Federation Development and Execution Process (FEDEP). As one of the Component-Oriented approaches proposed, FEDEP is able to obtain interoperability and reusability of available components, namely federates
