Abstract—To balance the tradeoff of the routing throughput in DTNs, we try to propose a new method to integrate the delivery predictability of ProPHET-Routing with our previous OOP-Routing, called OOPProPHET-Routing. Also, we have used the NS2 network simulator to verify our proposed routing method is better than before, and we have achieved a good tradeoff between the delivery ratio and the numbers of forwarding packets. In particular, when the size of buffer-queue is not enough or when the numbers of forwarding packets of Epidemic-Routing is tremendously increasing, the delivery ratio of this routing can easily exceed Epidemic. In other case, the delivery ratio is close to Epidemic but the amounts of forwarding packets are less than one-tenth. Moreover, we vary the value of the threshold to examine the effect of adjustment.
