[en] This thesis presents investigations performed on the IEEE 802.11 handover process in order to optimize the exploitation of exisiting IEEE 802.11 networks in vehicular communications. As IEEE
802.11 networks operate over a short range, a mobile station embedded in a vehicle faces frequent handovers leading to long disconnections. This work focused on two objectives. The first was reducing the IEEE 802.11 handover impact such that mobile users are allowed to be fully connected while they stay within the area covered by IEEE 802.11 networks. The second was optimizing the AP selection process in order to comply with the always best connected paradigm by identifying the best access points and the best handover location. These researches lead to the development of a context-based predictive handover mechanism that considers vehicle’s trajectory, road topology, and network deployment information to decide the best handover location and candidate access points.
