机会社会网络中基于社会关系的数据传输机制

Data transmission mechanism based on social relations in opportunity social network

提出了一种节点社会关系衡量算法(NSRM)。首先,通过分析移动节点的社会关系特征提取决策特征属性,用于研究移动节点社会关系的动态变化;然后,结合信息熵和特征选择的方法对节点的决策特征属性进行权重分配;最后,根据权重分配的结果来衡量节点社会关系,进而基于社会关系选择最佳的中继节点转发数据。实验结果表明:该算法可以有效提高数据的传输效率,降低传输延迟和路由开销。

A node social relationship measurement algorithm(NSRM)was proposed.Firstly,by analyzing the social relationship characteristics of mobile nodes,the decision-making feature attributes were extracted to study the dynamic changes of mobile nodes’social relationships.Secondly,with the information entropy and feature selection methods combined,the decision-making feature attributes of nodes were weighted.Finally,the social relationship of nodes was measured according to the result of weight distribution,and then the best relay node was selected to forward data based on the social relationship.Experimental results show that this algorithm can effectively improve the efficiency of data transmission,reduce transmission delay and routing overhead.
