%X <p>The selection of relay node will directly affect the data forwarding performance of opportunity network. Therefore the cost-efficient routing mechanism with delivery probability perception (DPP-CERM) in opportunistic networks is proposed. The probability of comprehensive encounter between nodes by combining the probability of direct encounter and indirect encounter is estimated and evaluated by indirect inter-meeting time between nodes. The relay node reasonably and forward data with very lower cost were chosen thereafter. It is shown that DPP-CERM can reduce the average overhead ratio of data forwarding at least 64.9%.</p>
