Probability routing algorithm based on historical throughput in DTN network

In delay tolerant network, data transfer depends not only on the number of node contacts, each contact is more dependent on their quality, because of this proposed a probability routing algorithm based on historical data throughput. Through evaluated the historical contact time and historical throughput two factors, to calculation forward probability, so that the high quality contact play a leading role of the forward probability. The simulation indicate that the algorithm is compared with the traditional routing can greatly increase the probability of data delivery ratio.
