In Vehicular Ad-hoc Networks (VANETs), vehicles cangain short connections to the Internet by using wireless accesspoints (AP). A significant part of the connection time isthe time required for acquiring an IP address via DynamicHost Configuration Protocol (DHCP). Depending on a vehicle’sspeed and the AP coverage area, DHCP can consumeup to 100 percent of a vehicle’s available connectiontime. We propose the IP Passing Protocol to reducethe overhead of obtaining an IP address to under one-tenthof a second. This is done without modifying either DHCPor AP software. We explore scalable implementations anddescribe the dynamics of the IP Passing Protocol. We alsoshow our protocol will significantly improve efficiency, reducelatency, and increase vehicle connectivity.
