WiMAX-WLAN Vehicle-to-Infrastructure Network Architecture during Fast Handover Process

Vehicular Network is becoming increasingly popular in recent years, Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) mobile communication mode can provide great variety of feasible applications. This paper provides the architecture design of a vehicular WiMAX-WLAN network proposed for surveillance implementations on railway environment. Mainly we focus on data transmission applications over V2I communications during fast handover procedure. For this reason we analyze the proposed IEEE 802.16e-802.11b/g/earchitecture for Vehicle-to-Infrastructure between two oncoming trains while moving in opposite directions with constant speeds during fast handover procedure. Finally, through OMNeT++simulator tool we evaluate the performance metrics of the vehicular wireless network simulation results based on handover performance.
