Opportunistic network (OppNets) routing protocols are improved to run in a situation in which it does not present a consistent end-to-end communication. The investigators of the Delay Tolerant Networks (DTN) team had aimed at the performance of routing protocols which use “Store-Carry-Forward” method. Delay Tolerant Networks routing presumes that the node buffer is unlimited. Thus, the condition for message arraying and dropping strategy, for each inclination is very risky and advantageous in such limited situations. This paper offers an effective eviction strategy to improve the PRoPHET routing protocol quality. This strategy adds to the PRoPHETv2 routing protocol, which is currently proposed FIFO by default. The investigators evaluate the influence of several parameters, including the message life/buffer time, based on the performance of the PRoPHET pertaining to delay, replication/hop number, and delivery ratio. This paper evaluates the influence of individual parameter along with the MOFO drop strategy. The effectiveness of the projected method is assessed and compared with various procedures according to metrics, for instance, overhead, latency, and delivery ratio. The simulation findings ascertain that the applied dropping strategy enhances the efficiency of PRoPHET routing compared to the other different dropping strategies.

PRoPHET的有效驱逐政策

机会网络（OppNets）路由协议经过改进，可以在不呈现一致的端到端通信的情况下运行。延迟容忍网络（DTN）小组的研究人员针对使用“存储-转发-转发”方法的路由协议的性能进行了研究。延迟容忍网络路由假定节点缓冲区是无限的。因此，在这种有限的情况下，对于每种倾向而言，用于消息排列和丢弃策略的条件是非常危险的，并且是有利的。本文提供了一种有效的驱逐策略，以提高PRoPHET路由协议的质量。该策略增加了PRoPHETv2路由协议，当前默认情况下建议使用FIFO。研究人员评估了几个参数的影响，包括消息寿命/缓冲时间，基于PRoPHET与延迟，复制/跳数和传送比率有关的性能。本文评估了各个参数以及MOFO下降策略的影响。根据度量标准（例如开销，等待时间和交付比率），评估了所投影方法的有效性并与各种过程进行了比较。仿真结果确定，与其他不同的丢弃策略相比，所应用的丢弃策略提高了PRoPHET路由的效率。
