摘要
针对无线传感器网络数据融合与路由面临安全威胁,从传感器数据融合过程的空间相关性和时间相关性入手,对LEACH算法进行改进,考虑节点的行为可信因素,提出了一种基于行为可信的安全数据融合与路由算法—BTSR。该算法通过检验传感器本地采样值构成的时空相似度与传感器数据融合过程统计特征的符合程度,保证了数据融合路由的安全和可靠。仿真实验表明BTSR算法在安全概率、能量消耗、融合精度方面比LEACH算法更具优越性。
In order to treat the problem of routing security in wireless sensor network, data fusion event was both spatially and temporally correlated. Low Energy Adaptive Clustering Hierarchy （LEACH） was improved and nodes＇ behavior trust was taken into account, a secure data fusion and routing algorithm based on behavior trust （BTSR） was proposed. The security and reliability of the algorithm were implemented by using statistical hypothesis test for matching the reading sequence of sensors and statistical characters of the data fusion event. The simulation results show that BTSR is better than LEACH on security probability, energy consumption and fusion precision.
