IPv6 auto-configuration VANET cross layer design based on IEEE 1609

In 1999, the Federal Communications Commission of the US granted 75 MHz bandwidth at 5.850–5.925 GHz frequency band for intelligent transportation system wireless communication between vehicles and roadside infrastructures to improve automotive user driving safety and comfort. For fast IPv6 global-link address auto-configuration in vehicular ad-hoc network (VANET), IEEE 1609.3 defines a frame ‘Wireless Access effort in the Vehicular Environment (WAVE) service acknowledge’ to replace router advertisement (RA); however, it violates the Transmission Control Protocol (TCP)/Internet Protocol (IP)-layered design. Hence the authors propose two cross-layer designs called router RA proxy and host RA proxy for WAVE systems to achieve quick IPv6 address auto-configuration, and both the designs are simulated in OPNET.
