Architecture réseau pour véhicule de transport en commun communiquant

With the growing popularity of mobile devices, Public Transport will have to evolve and will have to introduce new services to customers, like an Internet connection onboard for example. The vehicle will act as a mobile router providing its nodes with a reliable connection and therefore will be forced to stay connected to an access point at any time. Since network coverage area is restricted depending on communication technology and environment, performing handovers is mandatory, leading to network events affecting Transport protocols efficiency: latencies are introduced by network configuration, network parameters are changed brutally. This thesis studies such impact by focusing on its source before giving solutions aiming at lowering handover impact. Two means were chosen: lowering latencies introduced by network configuration and avoiding network parameters modification impact on Transport protocols.
