    In the context of vehicular networks a map updating application was analyzed, which enables vehicles to download relevant geographic data related to their position. Possible strategies for data sharing are the networks from infrastructure to a vehicle (I2V) and from vehicle to vehicle (V2V). In this study two chunking techniques, the Random Sort Strategy (RSS) and the Network Coding (NC), for the I2V network segment were compared. The study revealed that the distribution of different received chunks is independent of the file size when NC is used; when RSS is used the mean and standard deviation depend on the file size. The authors intend to integrate in a next step these results in the analysis of the V2V network segment.
