雾（从核心到边缘）计算采用大量无线嵌入式设备，使最终用户能够随时随地与任何地方进行连接。由于其工作性质，无线传感器节点往往无人值守，因此暴露于各种攻击。保护源位置隐私在无线传感器网络（WSN）应用中起着关键作用。针对能量收集传感器网络，提出了一种基于冗余分支收敛的保留源位置隐私方案（RBCPSLP），该方案在能量丰富的非热点区域产生大量路由分支，这些路由分支在到达热点区域之前可以合并成少数路由路径。然后，生成时间，路由的持续时间和路由分支的数量独立决定的基础上获得的能量，以最大限度地提高网络能量利用率，大大提高隐私保护，并提供较长的网络寿命。理论分析和实验结果表明，RBCPSLP计划允许几倍的提高网络能量利用率以及源位置隐私保护，同时最大限度地提高网络的生命周期。
Fog (From cOre to edGe) computing employs a huge number of wireless embedded devices to enable end users with anywhere-anytime-to-anything connectivity. Due to their operating nature, wireless sensor nodes often work unattended, and hence are exposed to a variety of attacks. Preserving source-location privacy plays a key role in some wireless sensor network (WSN) applications. In this paper, a redundancy branch convergence-based preserved source location privacy scheme (RBCPSLP) is proposed for energy harvesting sensor networks, with the following advantages: numerous routing branches are created in non-hotspot areas with abundant energy, and those routing branches can merge into a few routing paths before they reach the hotspot areas. The generation time, the duration of routing, and the number of routing branches are then decided independently based on the amount of energy obtained, so as to maximize network energy utilization, greatly enhance privacy protection, and provide long network lifetimes. Theoretical analysis and experimental results show that the RBCPSLP scheme allows a several-fold improvement of the network energy utilization as well as the source location privacy preservation, while maximizing network lifetimes.
