Poster: Address resolution for vehicular communications in heterogeneous environments

Vehicular communications have become very important in the recent years. Vehicles instantaneously form networks and utilize the available communication infrastructure. The vehicles' mobility is one of the major challenges in vehicular communications. In car-to-infrastructure communications, a vehicle is assigned an IP address through the network it is connected to, and thus mobility means a new IP address. In this work, we propose a NAT/Proxy-based solution to deal with the routing problem resulting from continuous changes of the IP address for vehicles while moving between different subnets.
