Routing and Address Assignment Using Lane/Position Information in a Vehicular Ad Hoc Network

Connection stability is important in vehicle-to-vehicle communication for applications that exchange messages for collision warning, cooperative driving, and other high-urgency purposes. Many of the existing communication protocols for mobile ad hoc networks assume the use of, portable gaming players, PDAs and other general-purpose devices, thus reducing the reliability of connection stability and communication. Therefore, greater efficiency can be expected by specializing systems for vehicle-to-vehicle communication using position information. To improve connection stability, we propose a method for constructing network groups according to lane position and evaluate the proposed method by simulation. We also describe a method of automatic assignment of IP addresses using IPv6 and a combination of network addresses defined for each lane and a specific host address for each vehicle.
