Location-Based IPv6 Address Configuration for Vehicular Networks

Due to long latency and considerable packet loss, stateful and stateless address configuration standards cannot efficiently work in vehicular networks, so this paper proposes an IPv6 address configuration scheme for vehicular networks based on location information. This scheme combines a stateless address configuration mechanism with a stateful one. In the stateless algorithm, duplicate address detection is performed within a road domain instead of a network. A random ID is introduced to reduce the address conflict rate, so the address configuration cost and delay are reduced. In the stateful algorithm, a vehicle acquires a unique address from a neighbor vehicle without recording the address allocation states, so the address configuration task is distributed around all vehicles and the distributed address configuration is achieved. This paper evaluates the performance of this scheme, and the data results show that this scheme reduces the addressing costs and delays.
