One of the main issues with Mobile Internet Protocol (MIP) is slow handovers. Mobility protocols are classified as micro or macro depending on the domain of the network. When macro mobility protocols are used in managing localized mobility requirements, they result in slow handovers and delays that result in loss of packets and make these protocols unsuitable for time sensitive applications. Mi...

Seamless mobility management of the mesh clients (MCs) in wireless mesh network (WMN) has drawn a lot of attention from the research community. A number of mobility management schemes such as mesh network with mobility management (MEMO), mesh mobility management (M(3)), and wireless mesh mobility management (WMM) have been proposed. The common problem with these schemes is that they impose unif...

Ce papier présente une recherche en cours sur l’exploitation des techniques de gestion et d’ingénierie des connaissances en vue de l’élaboration d’une démarche stratégique pour le transfert des savoir-faire métiers. Ce transfert se base sur la conception des dispositifs de partage et d’apprentissage à partir des connaissances bien identifiées, dans le domaine des métiers pétroliers. Ces travaux...

Prenant le contre-pied des discours sur travail comme mal nécessaire ou instrument d’aliénation, les compagnons du Tour de France cultivent depuis la fin XVIIIe siècle une forme distinction qui opère deux façons. D’une part, ils ne parlent qu’avec beaucoup retenue et parcimonie «travail». D’autre valeurs représentations associées à l’idée passent chez eux principalement par voies l’iconographie...

The IETF Mobile IPv6 protocol provides a mobility management scheme for the Internet. Mobile IPv6 handles macro-mobility and micro-mobility identically. We believe that a hierarchical scheme that separates micro-mobility from macromobility is preferable since it would be more scalable. In this paper, we present a mobility management architecture that makes use of the IPv6 Address format hierarc...

Laissez-faire leadership has received much less attention than have the 3 transactional leadership dimensions of the Multifactor Leadership Questionnaire (MLQ). However, laissez-faire leadership has shown strong negative relationships with various leadership criteria, and the absence of leadership (laissez-faire leadership) may be just as important as is the presence of other types of leadershi...

Mobility management is the fundamental technology to enable the seamless access to wireless networks and mobile services. Mobile IP is currently the most promising solution for mobility management in the Internet. The objective of this paper is to reconsider Mobile IP based mobility management solutions, with the emphasis on the proposal of new mobility management architectures. First, it is re...
