    Design of Wearable Health Monitoring Systems: An Overview of Techniques and Technologies&
    (Springer International Publishing, 2016) Boulemtafes, Amine; Badache, Nadjib
    Because 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.

    Wearable Health Monitoring Systems: An Overview of Design Research Areas
    (Springer International Publishing, 2016) Boulemtafes, Amine; Badache, Nadjib
    In 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.

    Providing Reliability for Transactional Mobile Agents
    (Vincent Guyot, 2013) Zeghache, Linda; Hurfin, Michel; Moise, Izabela; Badache, Nadjib
    A 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

    An Ω-Based Leader Election Algorithm for Mobile Ad Hoc Networks
    (Springer Berlin Heidelberg, 2012) Melit, Leila; Badache, Nadjib
    Leader election is a fundamental control problem in both wired and wireless systems. The classical statement of the leader election problem in distributed systems is to eventually elect a unique leader from a fixed set of nodes. However, in MANETS, many complications may arise due to frequent and unpredictable topological changes. This paper presents a leader election algorithm based on the omega failures detector, where inter-node communication is allowed only among the neighboring nodes along with proofs of correctness. This algorithm ensures that every connected component of the mobile ad hoc network will eventually elect a unique leader, which is the node of the highest priority value from among all nodes within that connected component. The algorithm can tolerate intermittent failures, such as link failures, network partitions, and merging of connected network components.
