%X Social network is a special kind of network, which includes mobile equipments carried by people , bus and other vehicle. Meanwhile, this network use the short-distance radio for communication. 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 Social Activity. And thus it proposed a node Social Activity based routing in the DTN. This routing schemes limit the next hop node according to the size of node Social Activity. Simulation results show that our routing strategies can improve the message delivery ratio, at the same time, greatly reduce the network overhead.
