| 1 | A Privacy Protection Strategy for Source Location in WSN Based on Angle and Dynamical Adjustment of Node Emission Radius显示文摘We propose two novel methods to improve the source location privacy security protection and the node energy utilization in Wireless sensor networks(WSN).A privacy preservation protocol for source location in WSN based on angles(APS) and an Enhanced protocol for source location(EAPS),which dynamically adjusts emission radius during routing.The APS protocol produces geographically dispersed phantom source nodes and utilizes the energy from the energy-abundant regions to make the routing path versatile among the entire network.In the EAPS protocol,according to the number of its own adjacent nodes,residual energy and the distance to the base station,a node adjusts its radius adaptively.Experiments show that the two novel protocols can improve the security and take advantage of the residual energy in the network balance the network life and energy consumption in comparison with the existing routing protocols based on the phantom sources. | JIA Zongpu WEI Xiaojuan GUO Hairu PENG Weiping SONG Cheng | 2017 | Chinese Journal of Electronics2017，26，5： | 3 |
| 2 | 无线传感器网络中双层受限中继节点放置算法研究显示文摘针对在三维空间中,对于中继节点(RN)的位置受限并且是双层拓扑的情况,提出了一种基于混合整数线性规划的中继节点放置算法,该算法首先考虑三维空间中继节点放置的物理层模型,然后基于混合整数线性规划(MIPS)给出最优能效的分簇,使得每个传感器节点与相应簇头之间的传输距离最小.仿真结果表明:与只考虑最小化簇内距离的中继节点放置算法相比,本算法在降低重传率和延长网络生命周期方面都有较大的改善. | 向浩凯 周小平 王家南 李莉 黄佳慧 | 2018 | 上海师范大学学报(自然科学版)2018，47，2： | 1 |
