基于社区发现的移动实体名字解析方法

Mobile Entity Name Resolution Method Based on Community Discovery

针对实体在移动过程中请求名字解析服务不能保证成功率的问题,提出一种基于社区发现的移动实体名字解析方法(MNR-CD)。该方法通过将用户的移动特征嵌入到解析节点构成的网络拓扑图,利用社区发现算法将节点划分到不同的社区,并计算社区内用户群体对节点存储名字的社区兴趣度,在被请求节点没有存储所需内容时将请求转发到社区内其他节点,以此提高服务可靠性。实验结果表明,本文提出的基于社区发现的移动实体名字解析方法比现场名字解析系统中现有机制在请求响应成功率方面有明显提高。

In order to solve the problem that the success rate cannot be guaranteed when the entity requests the name resolution service in the process of moving,a mobile entity name resolution method(MNR-CD)based on community discovery is proposed.This method embeds the mobile characteristics of the user into the network topology composed of resolution nodes,and using community discovery algorithm to divide nodes into different communities,and calculate the user groups within a community interest degree of node storage name.When the requested node does not store the required content,the request is forwarded to other nodes in the community to improve service reliability.The experimental results show this mobile entity name resolution method based on community discovery is significantly better than the existing mechanism of local name mapping and resolution system in terms of the success rate of request response.
