Abstract
In VANET, Vehicles can be seen as probes that locally detect traffic status. Various applications that target transport efficiency could make use of the vast information collected by the vehicles; however, this collection of information needs to be transported over larger distances. For this purpose, various protocols were proposed in the literature and are surveyed in this paper. The information dissemination ‘lifecycle’ is structured in four phases: obtaining information, transport of information, summarization of measurements, and aggregation of information. In this paper, we will focus on the first and second phases to insure the transport of information. And we improve the behavior of GPSR protocol in term of delay and throughput to deal with the limited capacity of the vehicular wireless network.
