Disruption-Tolerant Networking (DTN) is the technological tool for operating in networks that while performant are intermittently available and may lack end-to-end connectivity. Routing in DTN networks is an open research problem and there has been interest in tying DTN resiliency to Mobile Ad-hoc Networks (MANET) performance. Using the Multi Interface Communications Software (MICS) framework, we...
The traceability is a means to minimize the size of recalls and the production process. It is an emergent topic of research to improve the production efficiency. Some governments force the traceability on companies like a management tool of the risks in order to protect the public health. The objective of this work is to evaluate the impact of the RFID and WSN on traceability. We presented a categorization...
We are surrounded by different smart networked embedded devices that are running software dedicated to specific tasks. Many of these devices have no displays or user interfaces. To control and configure these devices remotely over network, instead of running factory-set static settings, devices need to be able to publish their parameters to a remote user interface of the system. In modular systems,...
In this paper, we presented a survey on intrusion detection systems (IDS). First, we referred to different mechanisms of intrusion detection. Furthermore, we detailed the types of IDS. We have focused on the application IDS, specifically on the IDS Network, and the IDS in the cloud computing environment. Finally, the contribution of every single type of IDS is described.
In this article, we propose a new approach to study a suitable structure of metamaterial antennas for RFID technology that operates in the UHF band. This antenna is constituted by a dipole associated to a network specific and homogeneous structure composite of circular split ring resonators that can produce a negative permeability. Thanks to the effect of effective negative permeability, we can improve...
This research paper reports in the Speech and Audio Processing Laboratory (SAP). Introducing the basic concepts of speech coding related to signal processing modules. The SAP Laboratory enhances the student's education through multimedia signal processing learning through speech and audio coding.
Mobile networks have experienced an unexpected penetration and continue to impress with their extensions and applications. Better yet, a growing demand there is for new services that require high speed and require a good quality of the connection. namely that the flow rate will be improved by the operation of a number of antenna both in transmission and reception, and that we will improve the quality...
A concise overview of Machine Type communication (MTC) is presented to encompass the various traffic patterns and models from the literature. Since M2M applications may well be generating huge traffic and resulting in bandwidth intensive transactions vying for priority, network operators must obviously be concerned about the handling of the enormous escalation in their signalling traffic and, in particular,...
TSV or interconnect between chips have as a promising solution for overcoming interconnect and power bottlenecks in 3D IC. However, testing of 3D ICs remains a significant challenge, and breakthroughs in test technology are needed to make 3D integration commercially viable. This paper first presents an overview of TSV-related defects and the impact of TSVs in the form of new defects in devices and...
Nowadays, the research and industrial communities are focusing their efforts on the adoption of Cloud computing for a massive interaction with the physical environment. At the same time the concept of Internet of Things (IoT), in which several embedded systems are interconnected over the Internet, is becoming more and more popular. In this context, the SIGMA project aims to exploit Cloud technologies...
Education data mining (EDM) is an emerging field which take advantage of natural language processing, data mining, statistics and machine learning algorithms for different types of educational data especially related to medical e-learning. Medical text categorization is the one of the major component to help students more easily and effectively search medical text for e-Learning. In this paper, spectral...
Image compression has attracted a lot of research since the beginning of Internet era and telecommunication. Enhancing image compression quality and ratio was achieved through several approaches such as neural networks and discrete transforms. However, other heuristic and bio-inspired methods such as genetic algorithms are still under experimentation. In this paper, we introduced a new image compression...
Energy consumption has become a major challenge in cloud computing infrastructures. Cloud computing data centers consume enormous amount of electrical power resulting in high amount of carbon dioxide that affects the green environment as well as high operational costs for cloud providers. On the other hand, reducing the energy consumption would negatively impact the SLA (Service Level Agreement) that...
Social media data and information become a real concern for many parties such as countries and organizations for analysis, strategies and decision making purposes. Selecting the best open source social media tool for collection and visualization data from social networks' web is a big challenge. In this paper, we propose an integrated approach to select the most appropriate tools for collecting and...
Adapting user interfaces to different contexts of use is essential to enhance usability. Adaptation enhances user satisfaction by meeting changing context of use requirements. However, given the variety of contexts of use, and the significant amount of involved information and contextual treatments, transformations of user interface models that consider adaptation become complex. This complexity becomes...
Clubfoot is a complex deformity found in one in a thousand children. It frequently causes disability — either from the original deformity or because of secondary conditions and problems associated with treatment. Recently, many pedorthsis supporting orthotics deformity in a foot have been evolved. Unfortunately, such pedorthsis need patients to involve in many doctor visits. The advance in wearable...
The diversity of interactions flows offers a large amount of information that can contribute significantly the interaction context-awareness at runtime. Particularly, users interventions can indicate accurately user's preferences and needs and can improve the personalization process. User's feedback looks promising to provide knowledge and assessment for an effective adaptation performance. However,...
The notion of travel time is a simple and necessary information for commuters, the intelligent traffic management allows to reduce congestion both temporally and spatially. In this context, this article focuses on the problem of estimating the route time where highway traffic is characterized by several macroscopic variables such as flow, intensity and velocity. We propose a probabilistic model based...
