- ItemDesign of Wearable Health Monitoring Systems: An Overview of Techniques and Technologies&(Springer International Publishing, 2016) Boulemtafes, Amine; Badache, NadjibBecause of the increasing costs of healthcare, wearable health monitoring systems (WHMS) are catching a lot of attention of the research community. Such systems are more and more propelled by advances in technology such as miniaturization, sensing devices and wireless communications. This study aims to review and synthesis the main implementation techniques and technologies used to design WHM Systems on the basis of the typical WBAN three-tiers architecture where the Body Area Network (BAN) represents the key infrastructure of such systems.
- ItemArchitecting the Internet of Things: State of the Art(Springer International Publishing, 2016) Abdmeziem, Mohammed Riyadh; Tandjaoui, Djamel; Romdhani, ImedInternet of things (IoT) constitutes one of the most important technological development in the last decade. It has the potential to deeply affect our life style. However, its success relies greatly on a well-defined architecture that will provide scalable, dynamic, and secure basement to its deployment. In fact, several challenges stand between the conceptual idea of IoT, and the full deployment of its applications into our daily life. IoT deployment is closely related to the establishment of a standard architecture. This architecture should support future extensions, and covers IoT characteristics such as distributivity, interoperability, and scalability. A well defined, scalable, backward compatible, and secure architecture is required to bring the IoT concept closer to reality. In the literature, several architectures have been proposed. Nevertheless, each architecture brings a share of drawbacks, and fails covering all IoT characteristics. In this chapter, we review the main proposed architectures for the Internet of Things, highlighting their adequacy with respect to IoT requirements. Firstly, we present IoT building blocks. Then, we introduce the high level architecture of IoT before diving into the details of each proposed architecture. In addition, we introduce a classification of the reviewed architectures based on their technical aspects, and their ability to match IoT characteristics. Finally, based on the main shortcomings of the proposed architectures, we conclude with some design ideas for shaping the future IoT.
- ItemWearable Health Monitoring Systems: An Overview of Design Research Areas(Springer International Publishing, 2016) Boulemtafes, Amine; Badache, NadjibIn order to be effective and helping towards improving quality of living of people, design and development of wearable health monitoring systems needs to satisfy a number of medical and non-medical criteria’s while taking in consideration resource limitations and fulfilling ergonomic constraints. This study with the aim to serve as a quick reference for future works, attempts to cover main research areas including requirements, challenges and tradeoffs related to the design of such systems.
- ItemProviding Reliability for Transactional Mobile Agents(Vincent Guyot, 2013) Zeghache, Linda; Hurfin, Michel; Moise, Izabela; Badache, NadjibA transactional agent is a mobile agent that migrates from a site to another one in order to execute a distributed transaction assigned by a user. Works on transactional mobile agents have identified two prob- lems that can not be solved by the agent alone. The first one is related to the reliability. The lack of a fault tolerant infrastructure and method- ologies that address fault tolerant execution of mobile agents highlights a major drawback of this technology. The second problem for which the agent needs assistance is related to the atomic validation of the transac- tion. In this paper we address the mobile agent fault tolerance and the transactional support
- ItemAn Architectural Model for a Mobile Agents System Interoperability(Springer, 2007) Zeghache, Linda; Badache, Nadjib; El Maouhab, AouaoucheAn important goal in mobile agent technology is interoperability between various agent systems. A way of achieving this goal would be to envisage a standard to be imposed on these various “agents systems” in order to allow the inter-working of various architectures of mobile agents. During the past years, different scientific communities proposed to different standardization actions, such as the Foundation for Physical Intelligent Agents (FIPA) and the Object Management Group’s MASIF (Mobile Agent System Interoperability Facilities). Although, they finally share some major targets, the OMG and FIPA current results show their distinct origins, particularly for interoperability between or within distributed systems. In this paper, we first analyze the similarities and differences, advantages and disadvantages of the Object Management Group (OMG) mobile agent and the Foundations for Intelligent Physical Agents (FIPA) intelligent agent approaches. Based on this analysis, we try to integrate these two standards to propose an architectural model for mobile agents system interoperability
