Handover Optimization in WiMAX Vehicular Communications
The WiMAX communications for vehicular is a topic of significant interest for research and industry communities, on both V2V (Vehicle-To-Vehicle) and V2I (Vehicle-To-Infrastructure) situations. This paper presents results of an experimental study, simulation based, directed to determine multi-dimensional regions where different lower layers parameters have influence on the overall handover performance in mobility scenarios, related to WiMAX V2I communications. The simulations results are consolidated in multi-dimensional graphs, named decision spaces. Based on them, optimal parameter sets can be provided by the network operator to vehicular mobile station, to guide its adaptation of the major WiMAX parameters to its speed and network topology and to help the handover decision.
