The enhancement of security inroads is an issue that has attracted the attention of many researchers and many studies have investigated this issue. One of the ways of avoiding accidents is to use health-related applications that use wireless networks to maintain communications. Vehicular ad-hoc networks (VANETs) is a domain of research in wireless networks. In this paper, the method of directed data dissemination was proposed for VANETs. The introduced method can be used by some health-related applications. This protocol can diffuse the intended data in the specified direction on the road. It can provide useful information for the vehicles, i.e. vehicles at the back of the road which are moving in a specific direction. The introduced algorithm tried to select the vehicle farthest from the source node in the data dissemination direction. In this study, an attempt was made to a base simulation of the proposed method on reality. The results of the simulation indicated that the proposed method, when compared with other methods, diffuses the data with a better packet delivery rate, lower delay and less network overload.
