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.

Participatory mobile sensing applications are becoming increasingly popular. The growing population of privately-held mobile smartphones enables a plethora of new services. One of the most promising application areas is collaborative traffic sensing. Here, smartphones are used as mobile sensors to collect and share relevant location information in order to reconstruct a global picture of the traffic situation in a monitored area. There are several challenges that need to be addressed in order to provide an efficient and ubiquitous service. In this talk we present how low-cost mobile smartphones can be used for such services without compromising the everyday usage of the device. We first test several sensing policies and evaluate how they affect location accuracy and battery life. We then perform a penetration rate study to identify the proportion of participants required to provide good service by varying several parameters. The outcome shows that if configured correctly, smartphones can be used as accurate mobile traffic sensors providing important information even at low penetration rates. [less ▲]
