针对无线传感器网络节点恶意行为和自身故障问题,将节点信任按其功能行为分为传感信任、融合信任和传递信任,提出一种基于功能信任的无线传感器网络安全数据融合方法,并利用局部相关一致性原理检测节点的传感功能行为.NS2环境下的仿真实验结果表明,该方法可以有效地避免恶意节点对数据融合结果造成的影响,提高了数据融合的安全性和可靠性,延长了网络的寿命.
Aiming at the malicious behavior and self-fault of nodes in wireless sensor networks, node trust is classified into sensible trust, trust of trust and trust of trust according to their functional behaviors. A method of secure data fusion based on functional trust in wireless sensor networks is proposed. Local correlation The consistency principle is used to test the sensing function of the nodes.The simulation results in the environment of NS2 show that this method can effectively avoid the influence of malicious nodes on the data fusion results and improve the security and reliability of data fusion and extend the network Life expectancy
