摘要
针对幻影节点与源节点之间跳数较少、分布区域集中以及传输路径不够多样化等问题,提出一种优化源节点位置隐私强度的保护策略。该策略可以增强幻影节点选取的多样性,有效避开攻击者的可视区。设置选取幻影节点的条件,将幻影节点待选区域利用源节点生成的动态随机数以及存储位置信息分层,确保幻影节点与源节点之间具有足够的安全距离。设置距离Sink节点最小跳数且距离相等的等邻居节点组成的集合作为一个虚拟圆环,当数据包到达虚拟圆环时随机选择传递方向,利用动态生成的跳数值逐跳传递,可以有效增强传输路径的多样性,延长攻击者的平均追踪时间。仿真结果表明,与传统策略相比,所提策略可以使源节点位置隐私的安全性更高。
In this study,a protection strategy is proposed to optimize the privacy strength of the source node location for mitigating problems such as fewer hops between the phantom node and the source node,concentrated distribution areas,and insufficient diversification of the transmission paths.Using the proposed strategy,the diversity of phantom node selection can be enhanced and the visual area of an attacker can be effectively avoided.First,set the conditions for selecting phantom nodes,and the dynamic random number generated by the source nodes,and the storage location information layering in the area to select phantom nodes ensures that there is sufficient safe distance between phantom nodes and source nodes.Then,set the set of neighbor nodes with the least number of hops from the sink node and equal distances as a virtual ring.When the data packet arrives at the virtual ring,the transmission direction is randomly selected,and the dynamically generated hop value is used to transmit hop by hop,which can effectively enhance transmission the diversity of paths extends the average tracking time of the attacker.Simulation results show that compared with the traditional strategy,the proposed strategy can enhance the privacy strength of the source node location.
