Performance Evaluation of a Message Suppression Controller in Vehicular-DTN without Road-Side Units

In our previous work, we proposed a method of Message Suppression Controller (MSC) considering Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. In this paper, we evaluate the proposed MSC method for Vehicular Delay Tolerant Networking (VDTN). The simulations for two scenarios are conducted considering obstacles (buildings), where MSC embedded in Vehicles (MSCV) 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), end-to-end delay, total replicated messages and storage usage as evaluation metrics. At least in terms of our simulation results, we observe that MSCV decreases the replicated messages even if the number of vehicles is increased.
