In this paper, the design of a truthful mechanism for prioritized medical packet transmissions in e-health networks is studied. Unlike most of existing works, we focus on beyond wireless body area networks (beyond-WBANs), and consider the absolutely prioritized scheduling, i.e., emergent medical signals have to always be transmitted prior to normal ones. In our model, medical packets arrive randomly...
While reducing costs and improving sustainability, a common goal for Smart Cities is to become more “liveable” for their citizens. By taking advantage of new information sources offered by the Internet of Things (IoT), cities can rely on sensing platforms to improve their service offer. These sensing platforms, however, raise new research challenges, in particular regarding Quality of Information...
There is a prominent connection between human health and human emotion. This connection has encouraged researchers to produce numerous applications in order to facilitate patients and therapists. In this paper, through a review study we highlight how the development of intelligent emotion aware e-health systems can facilitate patient's satisfaction, emotion wellbeing, and physical health, and improve...
Software defined networks (SDN) is perceived to have specific capabilities for utilization by network infrastructures automatically. The success of OpenFlow protocol is to decouple control plane from data plane completely. However, current SDN still regards the network as a group of devices rather than a holistic resource, and traffic monitoring and control only relies on network states but not including...
This work proposes the Quality-of-Service Monitoring and Controlling Driver (QoSMCD), a software-based mechanism that improves the Network-on-Chip (NoC) performance by controlling the packet injection rate, thus reducing link congestion without modifying the hardware. The proposed mechanism works together with the task scheduling policy for controlling the injection of packets into the NoC. This work...
This paper presents results of the ongoing development of CYCLONE as a platform for scientific applications in heterogeneous multi-cloud/multi-provider environment. In particular, we focus on QoS management of the multi-cloud applications within CYCLONE. A challenging factor for application deployment and exploitation within the CYCLONE infrastructure is its highly dynamic nature, which raises the...
The knowledge of service performance of cloud providers is essential for cloud service users to choose the cloud services that meet their requirements. Instantaneous performance readings are accessible, but prolonged observations provide more reliable information. However, due to technical complexities and costs of monitoring services, it may not be possible to access the service performance of cloud...
Different services are separated by independent train ground communication networks in existing urban rail transit systems. Most of the independent train ground communication system are using IEEE 802.11 based WLAN technologies, which has many drawbacks when used in urban rail transit system, such as high speed performance degradation, open free frequency, etc. In this paper, we design a train ground...
A Smart Grid system involves many applications, such as power grid state monitoring and control, demand response, distribution automation, distributed generation and microgrids. They will generate a large volume of data traffic over the grid with different quality of service (QoS) requirements, which present challenges to the existing network architecture and protocols. In this paper, we propose to...
Software Defined Networking is a novel network architecture, which separates data and control plane by OpenFlow. The feature of centralized control to acquire and allocate of global network resource. So, the link load-balancing of SDN is not as difficult as the traditional network. This paper proposes a link load-balancing algorithm based on Ant Colony Optimization(LLBACO). The algorithm uses the...
Increasing usage of OTT (Over-the-top content) and IPTVservices on mobile broadband access networks leads us to find out content aware QoS mechanisms on new generation mobile core networks. SDN/NFV is key technology for future generation mobile networks. Cellular core network functions can be virtualized and programmable with SDN/NFV approach. In this work we discuss SDN/NFV based QoS mechanism based...
Monitoring the global state in peer-to-peer networks through decentralized mechanisms allows targeted optimization and improvement of the peer-to-peer network. However, malicious nodes could aim to distort the process of gathering the global state through monitoring. In this paper we propose DOMiNo, a security solution for tree-based peer-to-peer monitoring mechanisms. It passively listens to incoming...
As communication is the most fundamental resource for a smart city, it cannot allow any disruption with the related services. Therefore, real-time monitoring systems for the QoS state for the communication infrastructure are vital. Such systems that can detect communications failure can be used also for redeploying emergency and ad-hoc communications infrastructures. Sudden-Onset Disasters (SOD) typically...
Traditional unreliable failure detectors are per process oracles that provide a list of nodes suspected of having failed. In [Rossetto et al., 2015], we introduced the Impact failure detector that outputs a trust level value which is the degree of confidence in the system. An impact factor is assigned to each node and an input threshold parameter defines an impact factor limit value, over which the...
In view of the heterogeneous characteristics and enormous connections of the underlying networks in Internet of Things(IOT), we proposed a SDN-IOT architecture including physical layer, control layer and application layer in this paper. Based on this architecture, we designed a robot welding monitoring system. Considering a large number of different QoS requirements of data flows in IOT, we proposed...
The telecommunications sector is experiencing a large growth due to the variety of technologies, and also thanks to the exponential increase in traffic due, firstly to the continuous increase in the number of users and also to arrival services varied in high demand in quality of service (video on demand). In order to solve problems of growing customers and for offering a good quality of service of...
Mobile cloud computing (MCC) is the most promising cloud solution for the future mobile environment. It aims to integrate mobile devices with cloud computing, and provide to mobile users an online access to unlimited cloud resources. Furthermore, MCC has changed the concept of mobile devices from primitive gadget to full computers that accommodate work, personal and mobility needs. Thus, in this paper...
The maturity of hardware virtualization has motivated Communication Service Providers (CSPs) to apply thisparadigm to network services. Virtual Network Functions (VNFs)result from this trend and raise new dependability challengesrelated to network softwarisation that are still not thoroughlyexplored. This paper describes a new approach to detect ServiceLevel Agreements (SLAs) violations and preliminary...
