Abstract
In this paper, a new transmission approach is proposed for bundle protocol (BP) of delay/disruption-tolerant networking (DTN) adopted for use in deep-space communications. It is intended to achieve highly reliable deep-space file transfer over unreliable space channel which may experience unpredictable or random link disruption events or any other events that lead to burst data losses. The main idea of the proposed approach is to use a hybrid of theproactive retransmissionandactive retransmissionduring file transfer, with each employing different time intervals for the bundle’s custodial retransmission timeout (RTO) timer. The reactive retransmission is to provide additional transmission reliability in case the reliability provided by the proactive retransmission was not achieved due to the unpredictable link disruption events. Analytical modeling is presented for performance analysis of the approach, and the built model is validated by the file transfer experiment.
