    • 摘要: 在无线传感网络定位算法中,锚节点位置决定了节点定位精度.为此,提出基于高斯-Markov模型的移动锚节点的节点定位(GM-MAL)算法.GM-MAL算法基于高斯-Markov移动模型,提出自适应锚节点的移动路径规划,通过速度调整策略、垂直平分线策略、虚斥力策略以及虚引力策略规划路径.在定位阶段,将非凸优化问题转化为双凸形式,再利用交替最小算法(AMA)求解,进而获取更短的锚节点移动路径.实验数据表明,引入虚引力策略提高了路径规划精度,覆盖了更多的监测区域.此外,相比于线性算法,GM-MAL的定位精度得到提高.

    • 摘要: In order to improve the localization accuracy of wireless sensor networks,the node localization algorithm based on Steffensen iteration and fuzzy information is proposed.This paper introduced Steffensen iterative refinement to improve the positioning accuracy.Anchor nodes are divided into static anchor nodes and mobile anchor nodes,the algorithm uses the motion of the moving anchor node to assist the static anchor node to locate. Firstly,the location of unknown nodes is roughly located by using the fuzzy information between nodes,and then the node positions are it-eratively refined by Steffensen iteration to realize the precise localization of unknown nodes.The simulation experi-ment proves that the algorithm in this paper not only reduces the location error rate,diminishes the communication overhead,but also improves the node location efficiency compared with the 3D-ADAL algorithm and the improved TOF algorithm.%为了提高无线传感器网络节点定位精度,提出了一种基于Steffensen迭代和模糊信息的节点定位算法.算法在模糊信息定位方法的基础上,通过引入Steffensen迭代求精提高节点定位精度.算法将锚节点分为静态锚节点和移动锚节点,利用移动锚节点不断的运动来辅助静态锚节点进行定位.首先利用节点间的模糊信息实现未知节点位置的粗略定位,然后利用Steffensen迭代对节点位置进行不断迭代求精,以实现未知节点的精确定位.通过仿真实验证明,相比3D-ADAL算法和改进的TOF测距算法,本文算法不仅降低了定位误差率,减小了网络的通信开销,还提高了节点定位效率.

    • 摘要: 在基于移动锚节点的无线传感器网络定位过程中,移动锚节点的路径规划问题对定位性能有着重要的影响,但现有的路径规划方法没有充分考虑到网络内未知节点的密度以及分布情况,定位效率低且成本大,因此提出了一种基于方向决策的移动锚节点动态路径规划方法CWDP(Dynamic Path Planning Based on Orientation Decision-Classed Weighted).首先网络内的未知节点根据连通度阈值对自身进行分级处理,当移动锚节点进入网络区域后,根据通信范围内未知节点的反馈信息,再利用分级权重系数实时决策下一目标的移动方向.仿真结果表明,该方法有效地提高了网络内未知节点的定位覆盖率和降低了定位误差,并节约了定位成本.%In the process of wireless sensor network location based on mobile anchor nodes,the path planning prob-lem of mobile anchor nodes has important influence on the positioning performance. However,the existing path plan-ning method does not take full account of the density and distribution of unknown nodes in the networks,the positio-ning efficiency is low and the cost is large. Therefore,a dynamic path planning method of mobile anchor node based on direction decision is proposed ( Dynamic Path Planning Based on Orientation Decision-Classed Weighted, CWDP). Firstly,the unknown nodes in the network are graded according to the connectivity threshold. When the mobile anchor nodes enters the network area,according to the feedback information of the unknown nodes located in the communication range,the mobile anchor next moving direction is determined by using the hierarchical weight coefficient in real time. The simulation results show that the proposed method can effectively improve the localization coverage,reduce the localization error of the unknown nodes in the network and save the localization cost.

    • 摘要: In view of the problems of many anchor nodes are needed,low positioning precision and high positioning cost of the weighted centroid localization(WSL)algorithm,a WCL algorithm needs more anchor nodes. An improved WCL algorithm,WCL triangle received signal strength indication (RSSI)hop (WCL-TRH)based on single mobile anchor node aided is proposed. A mobile anchor node moves along the fixed route in monitor area, and broadcasts data packet in specified position;according RSSI ratios received by unknown node and minimum hops,weights are determined,the coordinate position of an unknown node is estimated. The simulation results show that the improved algorithm effectively improves the precision of positioning and stability,at the same time,reduce the costs of positioning.%针对加权质心定位(WSL)算法所需锚节点数目较多,定位精度低,定位成本高等问题,采用单个移动锚节点沿着既定的轨迹在监测区域移动,并在规定位置广播数据包;未知节点根据接收的信号强度(RSSI)比值以及邻居节点间的最小跳数确定权值,进而估算未知节点自身的坐标位置.仿真结果表明:算法有效地提高了定位精度和稳定性,降低了定位成本.

    • 摘要: The existing mobility strategy of the anchor node in wireless sensor network (WSN) has the shortcomings of too long moving path and low positioning accuracy when the anchor node traverses the network voids area. A new mobility strategy of WSN anchor node was proposed based on an improved virtual forces model. The number of neighbor nodes and the distance between the neighbor nodes to the anchor nodes were introduced as their own dense weight attributes. The unknown nodes in-tensity was used as weights to improve the traditional virtual force model. Meantime the distance-measuring errorε was taken into account. The optimal distribution, direction selection, shift step length and fallback strategy of anchor node could be ana-lyzed by the trilateration. Using the number of virtual beacon received by the unknown node and the distance between the un-known node to the anchor node calculate the virtual force. Then according to the virtual force, the direction was chosen and the anchor nodes were moved. Simulation experiments show that the strategy can make the anchor nodes move according to the specific circumstances of unknown node distribution. It has a high positioning accuracy and strong adaptability. It can success-fully shorten the path of the anchor node movement and reduce the number of virtual beacon. Moreover it can effectively avoid the anchor node to enter the network voids area and reduce the number of collinear virtual anchor nodes.%针对现有无线传感器网络(WSN)锚节点移动策略不能有效避免遍历网络空洞区域时引起的移动路径过长、定位精度低等缺点,提出一种基于改进虚拟力模型的无线传感器网络锚节点移动策略.将未知节点的邻居节点数量及其到邻居节点的距离作为自身的密集权重属性,利用未知节点的密集度作为权值来改进传统的虚拟力模型.同时考虑测距误差ε的大小,利用三边测量法分析锚节点的最优分布情况、方向选择、移动步长、回退策略.使用未知节点收到的虚拟信标数量与其到锚节点的距离计算未知节点到锚节点的虚拟力,根据所受虚拟力的大小进行方向选择并进行移动.仿真实验表明,该策略可使锚节点根据未知节点分布的具体情况进行移动,有较高的定位精度,适应性强,成功缩短了锚节点的移动路径,降低了虚拟信标的数量,同时还能够有效避免锚节点进入网络空洞区域,减少了共线虚拟信标节点的数量.
