Geonetworking and the corresponding routing protocols play an important role in application of Vehicular Ad-hoc Networks (VANETs). This paper presents the architecture and implementation of CLWPR (Cross-Layer, Weighted, Position-based Routing), a position-based routing protocol optimized for VANETs in NS-3 simulation environment. It utilizes mobility information from nodes and cross-layer information from PHY and MAC layer in order to increase its efficiency and reliability, respectively. More specifically, we present the changes that have been introduced to facilitate geonetworking, as well as the carry-n-forward mechanism. In addition, we developed a basic navigation facility that can provide information about the road and distance between two nodes.
