© 2013, Taysi and Yavuz; licensee Springer.Inter-Vehicle Communication (IVC) is an important component of the ITS architecture, that enables Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. GeoNet project brought the IVC one step further by enabling transparent IP connectivity between vehicles and the infrastructure. Specifications produced by the GeoNet project have been incorporated into several ETSI standards, which define the geonetworking protocol layer and the IPv6-over-geonetworking adaptation layer. In this paper, we propose an ETSI complaint geonetworking protocol layer on the well known NCTUns simulation framework. We discuss the architecture of our implementation as well as NCTUns specific issues encountered during the implementation. We believe that, with this contribution, the researchers are provided with a scalable and flexible framework with Berkeley socket API access to applications and SQL based performance logging for post simulation evaluations.
