Secure Localization Algorithm with Parameter Masking for Note Network
The parameter masking secure localization algorithm for wireless sensor network(WSN)is used to study the issue of secure localization service in WSN.A parameter masking secure localization algorithm for wireless sensor network is proposed.The network localization area is divided into evenly distributed grid phases,and the parameter masking communication signal is designed for the multi-hop node network with malicious nodes participating in the localization,which contains the number of hops and position information.Each hop parameter masking signal in the network is superimposed along the multi-hop path to generate the superim-posed signal index phase with the multi-hop path.The phase angle of the parameter masking signal is solved hop by hop and matched with the phase index matrix.The malicious node forwards the superimposed multi-hop masking signal,which makes the estimated po-sition and hop information difficult to match with the phase index matrix,so as to screen out the multi-hop path attacked by the mali-cious node.The identity information of nodes in the network is used to extract malicious nodes,and relocate legitimate nodes.Through experimental testing,the parameter masking signal with multi-hop superposition eliminates the attack of malicious nodes on the network and effectively suppresses the influence of malicious nodes on the positioning accuracy of legitimate nodes.
