摘　　要：本文针对嵌套移动网络中所存在的路由优化问题和数据包多层封装问题,借鉴移动自组织网中的多跳转发思想,提出了一种新型的路由优化模型.在该模型中,移动路由器可以直接选择被访问网络的固定路由器作为自己的外地接入路由器,进而消除了嵌套的影响.分析结果表明,相对于传统解决方案而言,该模型可以有效解决移动网络中由于嵌套而产生的路由优化问题,具有最小的数据包封装开销,并且对安全和快速切换等有着良好的支持.Route optimization for nested mobile networks is one of the major challenges in NEMO （Network Mobility） research. Current solutions have too much additional communication cost and make the existing protocols very, complicated. In this paper, we propose a new route optimization model to solve this problem. The basic idea is that a mobile router acts as an ad hoc node when it wants to select a foreign router as its point of attachment, which has mulfihop to it. Evaluation results show that our approach can solve the route optimization problem for nested NEMO has little additional communication cost and almost has no influence on the current protocols. Furthermore, our scheme has good adaptability to fast handoff scenario and security.
