So far, in most vehicular applications, navigation and communication are viewed as separate capabilities with little or no relationship between each other. Although much work has already been done related to the enhancement of vehicular communication protocols, they do not consider the leveraging of rich data sets provided by GPS receivers, such as position information, roadmap geometry, and traffic conditions, which would improve the utilization of the wireless medium and provide higher quality of service for a wide range of applications. With this goal in mind, we shall seek for opportunities to use GPS data at every layer of the communications protocol stack. The work presented in this paper aims to present the issues and provide solutions for a transport protocol for vehicular networks by using cross-layer optimization and geographic data to improve vehicular communications.
