基于信任机制的无线电环境地图重构
Radio Environment Map Reconstruction Based on Trust Mechanism
摘要
Abstract
The sensing nodes in the radio environment map system will be forced to transmit fake data to the data center after being captured,which leads to reduction of the accuracy of radio environment map.For this problem,an improved scheme of spatial interpolation algorithm based on the trust mechanism is proposed and the updating strategy of the trust value about the sensor is elaborated.The scheme reduces the weight of the malicious node's data in the spatial interpolation algorithm by changing the trust level of the nodes and after several times updating of the trust value the malicious node will be isolated in the end.In the experiment both Root Mean Squared Error (RMSE) and False Alarm Zone Ratio-Correct Detection Zone Ratio(FAZR-CDZR1) performance indexes demonstrate that the proposed scheme can prevent malicious nodes' data falsification attack effectively,and guarantee the accuracy of the radio environment map.关键词
