A Message Suppression Method for Vehicular Delay Tolerant Networking

The Delay/Disruption Tolerant Networking (DTN) aims to provide inter-operable communications with wide range of networks which have poor performance characteristics. In this paper, we propose a message suppression method for Vehicular DTN (VDTN) under highly stressed environment. The simulations for two scenarios are conducted considering obstacles (buildings), where Message Suppression with Road Side Units (MSRs) are present or not present. We consider 802.11p standard and send bundle messages in a Manhattan grid scenario. We use the Packet Delivery Ratio (PDR), duplicated bundle messages and end-to-end delay as evaluation metrics. Based on simulation results, we observed that our proposed method can reduce the duplicated message and the performance of mean PDR is higher than the results of Epidemic conventional method.
