一种改进的源节点位置隐私保护方法
An Improved Method of Source Node Location Privacy Protection
摘要
Abstract
There is always supposed to be an global listener in the sensor network,in order to protect the safety of the location privacy of the source node,an algorithm periodically sending the dummy data is proposed. In this method,nodes in a network periodically send dum-my packets to confuse the real data among them and prevent the attacker to determine the flow of the real data. In the meantime, the thought of setting up data threshold in every node are presented. When it stores the data above a certain threshold,it will be suspended to send any dummy data according to some strategies,preventing network congestion status. In the meantime,this thought can balance the network traffic control and save bandwidth resources. The network traffic analysis result shows that this algorithm is effective to protect the safety of the source node.关键词
