CLWPR - A Novel Cross-Layer Optimized Position Based Routing Protocol for VANETs. Katsaros, K., Dianati, M., Tafazolli, R., & Kernchen, R. In 2011 IEEE Vehicular Networking Conference (VNC) (VNC 2011), pages 200–207, 2011. abstract bibtex In this paper, we propose a novel position-based routing protocol designed to anticipate the characteristics of an urban VANET environment. The proposed algorithm utilizes the prediction of the node's position and navigation information to improve the efficiency of routing protocol in a vehicular network. In addition, we use the information about link layer quality in terms of SNIR and MAC frame error rate to further improve the efficiency of the proposed routing protocol. This in particular helps to decrease end-to-end delay. Finally, carry-n-forward mechanism is employed as a repair strategy in sparse networks. It is shown that use of this technique increases packet delivery ratio, but increases end-to-end delay as well and is not recommended for QoS constraint services. Our results suggest that compared with GPSR, our proposal demonstrates better performance in the urban environment.
