摘要:In this article, we propose an Opportunistic information dissemination protocol by mixing both flooding and an enhanced DHVN (Dissemination protocol for heterogeneous Cooperative Vehicular Network) protocol, allowing them to run opportunistically in a Manhattan plan. Special additional logic is added to the existing version of DHVN protocol in order to efficiently disseminate information in two steps: 1) by adding three tags, Initial Diffusion, Standard DHVN and DHVN Near Intersection; the Initial Diffusion tag is used for the first flooding transmission only and 2) by changing the SNF (Store and Forward) period by making it adaptive depending on the region. Detailed simulation results show that our opportunistic protocol outperforms the DHVN protocol by analyzing its performances using an integrated framework VNS.
