Abstract: 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.
