针对社会网络中每个节点移动区域的多少和在某个区域中停留时间的长短,给出了节点的社会活跃度(SA)概念,从而提出了在DTN网络中基于节点社会活跃度的路由.这种路由根据网络中节点的社会活跃度大小对下一跳节点进行限制.仿真结果表明,提出的路由在提高了递交率的同时,大大降低了网络开销.%With regard to a node of the mobile number of the region and residence time in a region in social network.This paper presented the concept of the SA.And thus it proposed a node SA based routing in the DTN.This routing scheme limited the next hop node according to the size of node SA.Simulation results show that the routing strategies can improve the message delivery ratio, at the same time, greatly reduce the network overhead.
