摘要： 针对在网络被毁伤以致分割后的路由重建和通信恢复问题，提出一种结合传统Ad Hoc路由和时延容忍路由的混合路由策略。采用按需选择时延容忍网络(DTN)路由的方式，使Ad Hoc路由失效后能利用DTN路由的时延容忍和网络容错能力继续路由。仿真实验结果表明，与PROPHET和AODV路由协议相比，该路由策略能在网络毁伤后快速重建路由，以保证近似毁伤前的高投递成功率，并利用局部的AODV路由缩短端到端时延。

Abstract: There is no feasible method to rebuild routing and reestablish communication in disconnected networks due to malicious attacks. This paper proposes a hybrid routing schema based on Ad Hoc routing and delay tolerant routing. On demand Delay Tolerant Network(DTN) routing schema is used to guarantee routing process based on DTN routing’s delay tolerant ability after failure occurring in adhoc routing. By evaluating packet delivery rate and end-to-end latency, the experiment proved that the proposed routing schema is a feasible method which can rebuild routing and reestablish communication efficiently and rapidly in disconnected networks. Not only high delivery rate can be guaranteed but also latency can be shortened by using local AODV.
