Enhances security for IMS client

However, NGN as proposed by the 3GPP implies significant challenges for the deployment. Indeed IMS architecture, which is considered as one of NGN network, includes significant security weaknesses for users and service providers. In order to increase the degree of confidence to the use of this network it is necessary to enhance the security of its different communication interfaces. To achieve this aim, we propose in this work a highlighting of the vulnerability in IMS access layer, focusing in possible attacks. We also propose a comparative study of existing security solutions in this field. This work will provide a significant improvement of existing solutions to enhance security for IMS user's access.

However, it is difficult and time consuming for teachers to give personalized suggestions to each student, particularly when there are many students in class. To cope with this problem, this study proposes concept-effect relationship model (CER) as a tool to identify the learning problem of students. Based on that, an intellectual learning guidance system has been proposed.

Content adaptation of learner's profile is an issue that concerns many researchers in education field. Several studies have been conducted to achieve high quality learning and adapt the content to learners' profiles.

The IMS (IP Multimedia Subsystem) import new taxation strategy flow based and QoS management policy-based. The QoS management poses a competition in terms of limitations of physical resources and the onset of congestion, which encourages more organisaton to look for management solutions other than DiffServ and IntServ. The NSIS (Next Steps in Signaling) appears as a magical solution that couples DiffServ and IntServ with other properties of control traffic to validate these properties and shows the integration with IMS we present this article. Our goal, in this article, is give an idea about a Framework that coupling NSIS and policy-based management in IMS, and experimentally verify results.
Towards an Intelligent System for Self-Correction of QoS in IMS Networks
2012 Sixth International Conference on Next Generation Mobile Applications, Services and Technologies, 2012

These solutions enable the integration of automatic correcting mechanisms for QoS deterioration, depending on network conditions and customer importance. However, the correction operation is costly in terms of resources and execution time. Face to this problem, the migration to an intelligent system based on reasoning based cases will enable the exploitation of recorded solutions for similar degradation cases. In this context, we propose a methodology for structuring both cases and recorded solutions in such a way as to minimize the research cost. This methodology can be held in two stages, the clustering for grouping similar cases and the classification for backup structure generation of event.
Towards minimizing author's effort during designing the domain model of adaptive web-based educational system

Among these systems, the adaptive web-based educational systems (AESs) were a promising research field. Designing and authoring such systems is not easy task. Thus, several tools were proposed in order to facilitate authors' jobs. However, in particular, authoring domain model still suffers the manual work. This paper presents an approach for minimizing effort of authoring process by allowing system being part of construction.

Nevertheless, most of them deal only with binary grades of each test item. In this paper, we present a new method to automatically construct concept maps based on fuzzy set theory that can construct concept maps based on the result of analysis of numerical testing scores. The proposed method can overcome the drawbacks of existing methods and provides a useful way to automatically concept maps in adaptive learning systems.
