嵌套移动网络在扩大通信范围的同时会带来严重的路由优化问题。针对已有优化方案在可部署性和性能等方面的不足提出了一种新的嵌套移动网络路由优化方案(NMNRO),通过扩展邻居发现协议,在嵌套移动网络内通告相同的外地前缀,并更新接入路由器的邻居缓存和移动路由器的路由表,然后通过向对端发送绑定更新来实现路由优化。性能分析表明,该方案为嵌套移动网络提供了较为完整的路由优化方案,在降低优化开销的同时,具有较好的可部署性和兼容性。仿真实验结果表明该方案具有较低的切换时延和较高的有效吞吐量,且这些性能优势会随嵌套层数的增加而更加明显。
Nested mobile networks face the challenge of route optimization (RO) even it can expend the scope of communications.The existing RO approaches have the limitation of low performance and difficulty of deployment.A nested mobile networks route optimization (NMNRO) scheme is proposed by extending the neighbor discovery protocol,in which foreign prefixes in nested networks are advertised,and the destination caches of access routers and the routing tables of mobile routers are updated accordingly.After that,a correspondent registration is performed in order to implement RO.Performance analysis shows that NMNRO provides an overall RO solution with lower overhead,better compatibility,and higher deployability.Simulation results demonstrate that NMNRO has lower handover delay and higher goodput than other schemes,and the performance advantage appears more significant with the increase of nesting level.
