A Message Suppression Controller for Vehicular Delay Tolerant Networking

In this paper, we propose a Message Suppression Controller (MSC) for Vehicular Delay Tolerant Networking (VDTN) under highly stressed environment. The simulations for two scenarios are conducted considering obstacles (buildings), where MSC with Road side units (MSCRs) are present or not present. We consider 802.11p standard and send bundle messages in a Manhattan grid scenario. We use the duplicated bundle received, end-to-end delay, number of sent messages, Packet Delivery Ratio (PDR) and storage usage as evaluation metrics. Based on simulation results, we found that our proposed method can reduce the number of sent messages in the network without reducing the PDR.
