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.
