Under the delay tolerant network, high mobility of the node and the transmission distance make it impossible to keep a durable and regular data routing path between two nodes. As a result, such failure affects the function of packet routing mechanism. Therefore, in order to improve the efficacy of data transmission, conventional delay tolerant routing adopts more packet replication, or makes opportunistic on-line with encountered nodes and selects advantageous ones to increase packet arrival rate or reduce transmission delay rate. However, excessive increase of packet replication or excessive records for selected transmission nodes may result in internet traffic or a waste of resources. It may also lead to a lower level of the routing protocol or a complicated operation. Thus, conventional delay tolerant routing is not satisfying. This research intends to design an optimized forward strategy on the basis of different routing algorithm. This strategy is based on adaptive socially aware and aims at improving solving problems of delay tolerant networks routing.
