A multi-agent approach towards cooperative overtaking in vehicular networks

This paper deals with the integration of agent technology in the emerging field of vehicular networks. The agents are empowered with domain knowledge and they can perform geospatial and temporal reasoning. For the domain knowledge we developed a vehicular network ontology. The geospatial reasoning is performed with AllegroGraph, while event reasoning in RacerPro. The vehicle overtaking scenario is used to exemplify our solution.

Benchmarking System for QoS Parameters

This paper presents the design and implementation of a benchmarking system for QoS (quality of service). The application generates traffic patterns, measures and computes the QoS parameters and stores and displays the results both in numerical and graphical form. The main advantages of this system are the traffic patterns complexity, the accuracy of the measurements and the user friendly interface. The application is developed in C# language for .NET platform and represents a part of a complex framework designed for developing QoS technologies such as traffic identification and marking, queue and congestion management, traffic shaping and policy, specific protocols.

Towards Improving Situation Awareness during Emergency Transportation through Ambulance-2-X Communication and Semantic Stream Reasoning

With the recent introduction of the eCall system, the cars involved in accidents exchange relevant information directly with the emergency healthcare services. For road safety, Vehicular Ad-hoc Networks can be used to exchange safety information between cars and ambulances, via vehicle-2-x communication. In this paper, we exploit recent advances in vehicle-2-x communication and the advantages of knowledge representation and reasoning in order to deploy cooperative communication for medical emergency services. The developed system continuously matches data retrieved from inter-vehicular communication with structured knowledge from vehicular ontologies and open street maps.

Intercloud platform for connecting and managing heterogeneous services with applications for e-health

The paper focuses on the problem of interconnecting different cloud providers with the aim of offering enhanced services. The Intercloud scenario is based on the key concept that any cloud by itself does not have infinite natural resources or stable geographic location. The paper presents a distributed architecture for interconnecting existing cloud services, from different cloud providers (Firebase, Windows Azure, Parse), in order to achieve a scalable and flexible infrastructure. To validate the proposed solution an e-health prototype (both software and hardware) for monitoring a medical device (a pulse sensor) was built.

Interconnecting Heterogeneous Non-smart Medical Devices using a Wireless Sensor Networks (WSN) Infrastructure

Smart hospitals enhanced through the Internet and related technologies with live monitoring and interconnected devices, using wired and wireless sensors, provide better health services for patients. However, legacy (non-smart) medical devices that are not able to communicate and to be managed by a smart hospital infrastructure are still in use. Patients’ data can be collected from a wide range of non-smart medical device. The paper introduces a novel concept, called WSNaaP (WSN as a platform) and a technical solution for interconnecting heterogeneous non-smart medical devices using an existing WSN infrastructure.

Problem-based learning and project-based learning concepts and their applications to engineering education

Several technical challenges should be taken into consideration when setting up hands-on laboratories, workshops and projects while the educational service providers need powerful, effective, stable and easy-to-use systems. In order to meet those requirements, such systems are designed and deployed as affordable services that request stability, reliability, availability, autonomy and resilience. This article presents an interactive learning system that complies with microservices architecture and supports individual study and collaborative learning approaches aiming at involving learners in solving problems on their own, then developing complex team projects based on individual contributions.

Collaborative learning tools for formal and informal engineering education

Microservices deployment of Rich Internet Applications is not a new research topic; many articles have been published and related innovative technologies released in the last years. Thus, the research work presented in this article is focused on surveying the current collaborative learning concepts and technologies and proposing a new virtual classware approach, implemented and deployed as a set of independent components responsible for specific collaborative learning services. While engineering education methodologies are complex, flexibility or openness should be considered as high priorities. Thus, an actual implementation, according to blended training scenarios, has been presented.

Simulation and Control of the Vehicles Movement in the Case of the Overtaking Procedures

In this paper, a solution for the simulation and control of the vehicles movement in the case of performing the overtaking procedures is proposed. In order to design the simulation system, the mathematical modeling of the vehicle movement is made, the obtained model being based on the state space representation. Also, the real-time working of the simulator is based both on the information obtained through the usage of a communication network between the vehicles and of the GPS-measured position. The main advantage of the proposed system consists in assisting the driver to perform a correct and a safe overtaking. Another original element presented in this paper is the including of the vehicle movement model in a control structure, resulting the possibility that the overtaking to be performed with a higher efficiency. The mathematical model, respectively the simulation system were tested and validated through some simulations associated to an overtaking scenario, simulations presented in this paper, too.

Development Tool for End-to-End QoS Sensitive Frameworks and Technologies

This paper proposes a software development tool for the development and testing of end-to-end QoS sensitive frameworks and technologies. The development tool is a modular software system, which allows researchers to assess the performances and functionalities of different QoS frameworks and technologies using an experimental methodology, rather than using simulation environments. We describe and analyze the behavior of the proposed development tool by testing, in a comparative manner, two end-to-end QoS frameworks: On-Demand QoS Path framework (ODP) and Self-Adaptive Bandwidth Reconfiguration QoS framework (SAR).
