面向多源信息采集的地理位置路由寻址机制

为满足日益增长的与地理位置相关的网络业务需求，在命名数据网络（NDN）的基础上，提出了面向多源信息采集的地理位置路由寻址机制.设计了地理位置编码方案，将地理位置信息与NDN中的内容名称结合起来，支持面向位置的多源信息采集请求；在原始NDN路由转发框架下，提出了基于自学习的地理位置路由寻址机制，避免了路由通告带来的开销，并可兼容传统的NDN路由转发机制；最后，使用ndnSIM仿真平台实现了该机制并进行了实验验证.验证结果表明了该路由寻址机制的有效性.

Geographic Routing and Addressing Scheme for Multi-Source Data Retrieval

In order to meet the emerging location-related network services, a geographic location routing and addressing scheme for multi-source data retrieval is proposed on the basis of named-data networking (NDN). By combining geographic location information with content naming in NDN, a geographic location coding scheme is designed to support location-oriented multi-source data retrieval requests; Moreover, based on the NDN routing and forwarding framework, a self-learning geographic location routing and forwarding strategy is proposed. The strategy avoids the overhead caused by routing advertisement and is compatible with the traditional NDN routing and addressing mechanism; Finally, the proposed scheme is implemented on the NDN simulation platform and verified by experiments. The result shows the effectiveness of the routing mechanism.
