Abstract : This thesis proposes a new method for providing network connectivity to vehicles over a predefined trajectory (trains, metros, urban buses, etc.). The communication between the vehicle and the infrastructure network is based only on WiFi technology. The contributions of this work are two-fold: 1) the horizontal handover (between WiFi access points) and 2) the design and analysis of an infrastructure network (backbone network plus WiFi access network) deployed along the trajectory of the vehicle. In the first contribution, we propose a handover scheme, called Spiderman Handover, which describes the horizontal handover for an in-motion network (on-board the vehicle) considering a procedure to update the routing information of a bridged infrastructure network (OSI layer 2). We evaluate our proposal by means of simulation and we validate our results by experimental measurements. In the second contribution, we study theoretically the parameters of several chordal like topologies in order to build a backbone network for a linear access network. By comparing these parameters, we propose a backbone network composed by a combination of two chordal topologies. This backbone network provides a good balance between their deployment cost, number of hops to the gateway of the network and a reasonable resilience. Finally, we evaluate the integration of this infrastructure network and the handover scheme by means of simulations. Results showed that the proposed handover scheme works properly on the proposed infrastructure network, allowing the provision of a continuous network connectivity to passengers on-board trains, metros or urban buses.
