Misbehavior of node represent a serious threat against routing in delay tolerant network. In this paper mainly focus to improve the packet loss during the transmission of packet one to another node and also deal with selfish and malicious node. In this paper introducing a periodically available trusted authority. TA judges any node in the network by collecting the history evidence from upstream and downstream node. TA could punish compensate the node based on its behaviors. Each node must pay deposit amount before it joins the networks, and the deposit will be paid after then node leave if there is no misbehaviors activity of node.
