This paper proposes a utility-value-based forwarding protocol (UVBFP), which uses the history information of the met between nodes to predict the chance of connection in the future. Based on the prediction, our method builds a utility computation model for setting up the connection between the node and the goal node. In our approach, we first define the node connectivity, node correlation degree, node frequent degree, node intimacy, connection time interval degree, node similarity and node mobile connectivity degree. Then, we calculate the utility value of the node from these factors. Finally, based on the history information of the node, we sort out the network topology information of the neighbors, and select the best nest hop relay node for data forwarding. Simulation experiments show that UVBFP is cost effective and has high delivery ratio.
