Résumé
NEtwork MObility (NEMO) introduces a new communication paradigm that provides sets of mobile hosts moving collectively as a unit with high mobility. The users of these networks may require Quality-of-Service (QoS) guarantees for their real-time multimedia services. To grant this requirement, seamless handover must be provided. Moreover, end-to-end resources should be reserved. In this thesis, we address both of these issues. To reduce the loss of packets and the latency involved in handover, when a mobile network moves from one access router to another, handover delay should be minimized. Our proposition lies in the cooperation of multiple mobile routers which are located in the same mobile network. That is, the traffic of the mobile router which is performing handover is transported by the other mobile router(s) which is (are) not performing handover. The task of resource reservation in NEMO, in this thesis, is split into three sub-tasks. The first is to release obsolete reservations along the old path. These obsolete reservations are caused by the departure of the mobile router. The second is to reserve resource for the next location in advance to avoid service interruption. The service may be interrupted when the mobile router moves to the new location, but resources for this new location are not yet reserved. The third is to aggregate individual per-flow reservations into one reservation.
