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.

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.

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).
