BTSR: Secure data fusion and routing algorithm based on behavior trust

ZHU Cheng,ZHOU Ming-zheng,XU Jin-sheng(Department of Computer Science and Engineering,Anhui University of Technology and Science,Wuhu Anhui 241000,China)  
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.
