面向多源信息采集的地理位置路由寻址机制

Geographic Routing and Addressing Scheme for Multi-Source Data Retrieval

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ndn SIM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.

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.
