Traffic classification allows network operators to gain important insights to better characterize packet flows, enabling fundamental applications such as traffic engineering, network analytics and Quality of Service (QoS) enforcing. A common approach adopted for flow classification is based on Deep Packet Inspection (DPI): all the traffic is processed by a middlebox whose task is the association of...
In this paper, we introduce the idea of exploiting the emotional information as a key element in providing personalized context-aware software services and consequently enhancing quality of User Experience(UX). We argue that emotional measurements can be integrated in Quality of Service (QoS) assurance frameworks. The idea builds on the strength of technological advances in emotion measurement tools,...
Hiking a relevant web service in the current environment full of various options is similar to looking for a needle in a haystack. The best possible web service is the one that completely fulfills the required functions while satisfying the QoS requested by a user. In this paper, we introduce a new context-based solution based on QoS (Quality of Service) exploiting both functional and non-functional...
This paper introduces a model to represent the information systems using a tactical service-oriented infrastructure (TSI) together with the orchestrations of core services providing the reactive/proactive connectivity mechanisms within TSIs in/out chains. The model was instantiated with services realizing an algorithm behaving differently under stable or unstable network conditions. A quantitative...
Software Defined Networking (SDN) is a rapidly emerging technology that brings new flexibility to networking through the separation of the control and data plane. This paper presents one SDN based framework, among several potential valid approaches, for addressing the mobility of operational nodes within a coalition environment. The operational nodes require mobility to enable roaming, multi-homing,...
The aim of this paper is to propose a framework analysis of urban bus transport service quality in Moroccan context. This framework is based on the principle of combining the user and the service managers, delegating authority and transport operator, vision and consists of three modules. Namely: Definition, evaluation and management of service quality. This paper will be carried out as follows: first,...
Isolating fine-grained business functionalities byboundaries into entities called microservices is a core activityunderlying microservitization. We define microservitization asthe paradigm shift towards microservices. Determining theoptimal microservice boundaries (i.e. microservice granularity) is among the key microservitization design decisions thatinfluence the Quality of Service (QoS) of the...
GPUs have been widely adopted in data centers to provide acceleration services to many applications. Sharing a GPU is increasingly important for better processing throughput and energy efficiency. However, quality of service (QoS) among concurrent applications is minimally supported. Previous efforts are too coarse-grained and not scalable with increasing QoS requirements. We propose QoS mechanisms...
Usability is considered as one of the most important quality factors for commercial Web interfaces, along with others such as performance and security. However, most of usability evaluation methods for these Web applications do not support automatic measures. This paper addresses these issues through the presentation of an automatic evaluation model based on a systematic qualitative technique to validate...
Cloud environment consists of many components playing different roles which need to interact with each other. Based on the context the nature of interaction may vary. Trust is an essential facet for confidence-based interactions among the various entities in cloud environment. This paper presents the taxonomy of trust models and classification of information sources for trust assessment in cloud paradigm...
Nowadays, the demands for composite services with devices such as sensors/actuators and Web services have increased [1]. Many kinds of cloud services that can connect to real world, as typified by image recognition or speech recognition has come into widespread use to address the limitation in information processing on devices. In that situation, sensors are also provided as sensor services that senses...
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...
Quality of Experience (QoE) becomes a topic of utmost eminence for service providers and the major factor in the success of multimedia services. Thus, it is challenging to investigate thoroughly the human side of QoE in order to find out the impact of factors that affect user satisfaction. In this paper, we provide a structured way to build an accurate and objective QoE model. In order to serve this...
In this paper, we present a user-centered approach, which ensures dynamic service discovery and composition. Besides, our proposed framework integrates self-adaptive mechanisms to adjust the service's execution to the user's context and the notion of the QoS in order to build a composite service or find services that fit a best. Additionally, our framework permits the re-composition of the composite...
Nowadays, composite service has led to a new challenge as there are various kinds of users and an increasing number of similar Web services. This challenge is to pick out the most appropriate composition for user requester. However, a composite service is determined by the quality of the involved Web services and some user preferences. Consequently, the best composition optimizes the QoS (Quality...
Authenticating users connecting to online services, social networks or m-banking became an indispensable element of our everyday life. Reliable authentication is a foundation of security of Internet services but, on the other hand, also a source of users' frustration due to possible account blocking in case of three fails. In this paper we propose a model of authentication service management which...
The orientation towards web service technology gives a raise to huge number of functionally similar web services. Hence, quality of service is becoming more important and even essential in web service technology as a distinctive criterion. Generally providers have sufficient information about the really provided quality, however, clients don't. Service level agreements that define the relationship...
Cloud computing has emerged as the primary and popular computing paradigm recently. Since cloud users move continuously, sustaining the required quality of service (QoS) in a cost effective manner is very challenging. For maintaining the required QoS for a moving user, the current cloud systems use some of the existing service replication or/and migration strategies. However, those policies become...
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 emerging research of SDN and NFV have been promising to provide flexibility in network provisioning based on service requirement. However, current network provision methods of SDN and NFV do not have a formalized model of describing dynamic requirement of the services. The usage of audio/video services may be the example of the services with dynamic requirement. The orchestrator of SDN and NFV...
