Despite of the evident success of the IEEE 802.11 standard, mobility support remains an open issue in networks based on this technology. Particularly, the management exchanges performed by the station during the handover (handover execution) affects the communication performance. Several work have been proposed to enhance the handover execution in IEEE(More)
Different re-authentication methods have been proposed to reduce the time needed to complete a handover. If the handover latency is an important criterion, network operators have to take into account a lot of parameters while designing their networks, such as signaling overhead, functional properties or deployability. In this paper, a comparison of several(More)
Ad hoc networks are composed of mobile nodes without any centralized management entity. The appearance and the disappearance of the nodes are managed in a distributed way as well as the operation of routing, which forces each node to become itself router. There is an important traffic overhead to maintain the network connectivity and to assume the data(More)
