Performance analysis of TCP handover in a wireless/mobile multi-radio environment

The European Union funded projects DRIVE (Dynamic Radio for IP Services in Vehicular Environments) and OverDRiVE (Spectrum Efficient Uni- and Multicast Over Dynamic Radio Networks In Vehicular Environments) aim at enabling spectrum-efficient high-quality wireless IP communication in a heterogeneous multi-radio environment to deliver in-vehicle multimedia services. The IPv6 based network architecture for IP over multi-radio access networks and traffic control aspects has been developed in the DRiVE project. This paper presents relevant results of a performance analysis by simulation of the TCP handover behavior in the DRiVE multi-radio environment. Furthermore, the OverDRiVE project extends the scenario to mobile networks in larger vehicles like busses or trains, which imposes further interesting challenges on the IP-based network infrastructure and their protocols. The TCP handover evaluation will be continued in both the DRiVE and OverDRiVE scenarios.
