Network mobility arises when a mobile router connecting an entire network to the Internet dynamically changes its point of attachment to the Internet. Such kind of network is referred to as a network that is mobile (NEMO). NEMO networks may lead to frequent handoffs between various access routers that are connected to the fixed network.

Mobile cellular networks are now largely deployed, and mobile customers are used to place and to receive calls at any location. The network coverage is continuous, but radio conditions met by users are not homogeneous. Thus, data rate is varying according to user mobility. In this paper, we propose to discriminate terminals by their radio conditions in(More)
Infostation systems, based on pico-cells, provide intermittent but very high speed rates. Many problems appear because of discontinuous coverage and the mobile environment (mainly service disruptions). These problems directly affect applications performance. In this paper, we propose a hierarchical architecture that enables the network to resolve these(More)
The progress of wireless communication technologies allows the implementation of high rate applications. Users want to use their mobile devices, equipped with a wireless interface, to watch videos and capture images and video clips. Indeed, these high rate applications can quickly consume the available radio bandwidth. In this context, classical mobile(More)
The infostations system, small and separated islands of coverage, provides intermittent but very high speed rate. The short time the mobile terminal spends in the coverage area has direct impacts on the network performance. Thus, it is essential to avoid the bandwidth wasting due to the overall delay by performing mobility prediction. A new mobility(More)
