摘要:
针对无线传感器网络源节点位置隐私保护中源节点安全时间较短这一问题,提出了一种基于距离和节点能量的 无线传感器网络源节点位置隐私保护方案(SLPDNE:source-locationprivacyprotectionschemebasedondistanceandnode energy)。 该方案通过在网络中源节点可视区外随机选择幻影节点的方式,避免了失效路径产生且使得幻影节点分布具有 地理位置的多样性。 随后在源节点至幻影节点路由路径中,以节点能量和距离信息作为计算依据,选择能量充足且与幻 影节点距离较近的节点作为下一跳路由节点,在源节点和幻影节点之间形成分散路由,避免了能量较少节点被选择的情 况,增加了路由路径的多样性和动态性。 理论分析和实验结果表明,该方案能够在不明显增加网络能耗的情况下,有效地延长源节点安全时间,增强网络中源节点的位置隐私保护能力。
Abstract:
In order to solve the problem of short security time of source node in source node location privacy protection in wireless sensor networks,a new source node location privacy protection method for wireless sensor networks based on distance and node energy (SLPDNE) is proposed. This method avoids the generation of waste paths and makes the distribution of phantom nodes geographically diverse by randomly selecting phantom nodes outside the visual area of source nodes in the network. Then,in the routing path from source node to phantom node,node energy and distance information are taken as the basis for calculation,and the node with sufficient energy and close distance to the phantom node are selected as the next hop routing node to form a diffusive routing between the source node and the phantom node,which can avoid the selection of nodes with less energy and increase the diversity and dynamics of routing path. Theoretical analysis and experimental results show that this method can effectively prolong the security time of source node and enhance the source-location privacy protection in the network without significantly increasing the network energy consumption.
