Abstract The concept of group recommendation （GR） is presented. Based on group recommendation, a novel dynamic trust model for multi-hop wireless network is proposed, which overcomes the disadvantages of trust models existed in current movable self-organized network. More precise trust judgment for the cooperation and communication between nodes can be provided through integrated evaluation on the node＇s behavior in model. Furthermore, the status change of trust relationship can be revealed, and the integrative trust criterion between the nodes can be established effectively. This new method can stand against the cheating behavior from hostile nodes preferably, which solves the problem of blind trust effectively during the authentication process in multi-hop wireless network.
