【摘要】 在物联网中存在着一系列的攻击,攻击者可以通过一系列手段,如流量检测、反追溯等进行源节点定位,其中源节点是指在监控监测目标的时候,离被检测物较近,第一时间获得监测数据并向通过多步向汇聚节点发送信息的节点,并且试图获取监控目标的位置,一旦攻击者在一定时间内检测并定位到源节点的位置,就意味着监控目标已经暴露。由于物联网主要应用在开放的不安全环境中,传感器节点大部分是低能耗,低处理能力,低存储能力,在室外部署完成网络后,几乎就是无人的自动运行状态,此时源节点的保护显得很重要。更多还原

【Abstract】 In wireless sensor networks,attackers via a series of measures,such as detection of flow or anti-retroactive to locate the positioning of the source node.The source node is the one which is closer to the detected objects than others;it will obtain monitoring data in the first time,and then send information through multi-nodes towards to the sink node.Also attempts to obtain the location of the monitoring objectives.Once the attacker detects the location of the source node within a certain time,it means that the object has been discovered.Since the main applications of wireless sensor networks are in the open environment,they are unsafe.And most of the sensor nodes are low power provided,low processing capacity,low storage capacity,when the network is completely deployed,it will be almost automatic operate,then the position of source node protection is very important.更多还原
