A Recovery Method for Reducing Storage Usage Considering Number of Neighboring Nodes in VANETs

In Vehicular Ad-hoc NETworks (VANETs), end-to-end communication becomes difficult because of dynamic change of network topology caused by high mobility of vehicles in the network. In order to deal with this problem, Delay/Disconnection/Disruption Tolerant Networking (DTN) can be a good approach. However, consumption of network resources and storage usage of each vehicle is a critical problem in VANETs. In this paper, we propose a recovery method for reducing storage usage of each vehicle for VANETs without additional message exchanges. We evaluate the proposed method by simulations. In this paper, we found that the proposed recovery method can manage the storage efficiently for a limited density of vehicles.
