摘要:
当传感器网络中存在一个全局监听者的情况下，为了保护源节点的位置安全，文中提出了一种周期性发送干扰数据的算法。网络中的节点周期性地发送干扰数据包，将真实数据混淆在其中，攻击者无法判断真实数据的流向，从而保护了源节点的安全。同时，文中提出在每个节点中设立数据门限的思想，当节点中的数据超过一定门限值，将根据一定策略暂缓发送干扰数据，从而防止网络拥塞等状况的出现，同时能平衡网络的流量状况，节省资源带宽。从网络流量分析结果可知，该算法有效地保护了源节点的安全
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
