(English Abstract)
Vehicular Delay Tolerant Networks (VDTNs) have been proposed to address the communication challenges through the store and forward techniques. These techniques employ the intermediate nodes, which take custody of the data and forward them when is possible, but this method could generate congestion and lost packets if the intermediate nodes are not properly selected. However, the selection of the intermediate nodes remains as a central challenge. Therefore, we propose an efficient destination-based algorithm for dynamic custodian management by selecting the intermediate nodes according to the importance of the message, destination, current location and speed of the vehicles. An experimental evaluation was performed with real traces of taxies in the Shanghai city to show the feasibility and assess the performance of the approach. The results revealed an outstanding performance in terms of delivery ratio.
