中文摘要：
名字路由已成为未来网络的研究热点之一,由于网络中节点和信息规模的持续增长,可扩展问题成为其瓶颈。几何路由作为新型可扩展路由方案,可同时满足路由表规模和路由路径的可扩展,但难以支持名字路由。首先在几何路由基础上提出了一种通用的基于位置无关名字的可扩展几何路由方案——GRIN,结合源路由和贪心路由实现混合几何路由,在混合几何路由上引入基于双层稀疏群组的名字解析（映射）。然后理论分析了节点状态及名字映射的路径延展度上界。最后通过仿真验证了GRIN具备可扩展、低延展度以及高可靠性等特征,并优于其他名字路由方案。
英文摘要：
Name-based routing has become one of the hot topics in future network. However, due to the sustained growth of the size of nodes and information, the scalability issue is becoming one of the bottlenecks of name-based routing. As a new type of scalable routing, geometric routing provides both scalable routing tables and low routing paths, but it is difficult to support name-based routing. A universal scalable geometric routing scheme based on location-independent names （GRIN） was proposed. GRIN implemented a hybrid geometric routing（HGR） combining greedy routing with source routing, introduced a distributed name resolution using 2-level sloppy groups. Then the state and the path stretch upper bound of GRIN were analyzed. The simulation results show that GRIN guarantees scalability, low stretch and reliability. It outperformanced other similar routing schemes.
