Age of Information Optimization

The dissemination of redundant copies of a message is one of the techniques used in Delay/Disruption Tolerant Networks (DTN) to improve the delivery rate and to decrease the incurred delay. Nevertheless, many of these copies remain in the buffer of intermediate nodes even after the message is delivered to the destination. In this paper, we propose mechanism to remove obsolete messages for DTN routing protocols. Furthermore, we compare its performance with other state-of-art techniques under two different realistic scenarios and using two datasets of human mobility traces. Through the obtained results, we observed a better performance of the tested DTN routing protocols in most scenarios in terms of delivery ratio and overhead messages, when compared to others related works.
