摘要: 传感器网络中,节点中的噪声将会导致数据的不确定性。人们总希望在不确定情况下和有限带宽内使系统获得最大利益。而节点代理却是自私的、理性的,并且要使自己利益最大化。这时信任问题变得非常重要。把Certain Trust(CT)信任模型用于多传感器网络的信息交易中,使代理在交易过程中选择诚信可靠和信息质量好的代理进行合作,从而使自己收益最大,系统收益最大。用程序模拟实验,结果表明了该方案的优越性。

Abstract: Noises in a node usually cause uncertain data in Multi-Sensor Networks(MSN).People want the best social benefit under such circumstances and with limit band-width,but the node agents are selfish and rational,and always want to maximize their gains,so the trust is a very important factor.Thus,the Certain Trust(CT) model is applied on MSN.The sensor can pay fewer premiums for a better POS(Possibility of Success) to complete the task,and maximize their gains from a market and obtain the best social benefit at the same time.It is simulated by java program and good performance is achieved to prove the superiority of this scheme.

Key words: uncertainty, trust model, CT trust model, sensor network
