Overhearing Assisted Optimization of Address Auto-Configuration in Position Aware VANETs
Vehicular networks allow vehicles to exchange information that can be used to improve traffic efficiency and drivers' safety. In addition to these new applications, Internet connectivity is also expected to be available in the cars of the near future, speeding up the global adoption of vehicular communication systems. One of the requirements for connecting vehicles to the Internet is their ability to auto-configure IP addresses. In this paper, the authors propose an optimization to Geographically Scoped stateless Address Configuration (GeoSAC), which is an IP address auto-configuration mechanism for geographically aware location vehicles. The benefits of this optimization are two-fold: it can reduce the IP address configuration time, and it can be used to reduce the signaling overhead of GeoSAC.
