Abstract

In Delay/Disruption Tolerant Networks (DTN), the buffer space control is an important factor for its operation. A way to avoid buffer saturation is the use of mechanisms to remove copies of messages already delivered at destination, that are still occupying buffer space at intermediate nodes. However, such removal mechanism only start to act after messages deliveries at destination. Thus, the focus of this work is to investigate the use of a mechanism that removes copies of messages jointly with buffer management policies (Random, FIFO and LRF) in the evaluation of a DTN using the Epidemic routing protocol.
