Description: 提出了基于无线传感器网络的浮标网络水下GPS定位系统模型，分析了
该模型的结构、功能以及工作过程，并从几何角度探讨了水下目标的声学定位算
法。结合Range-Free算法与分布式算法的思想，设计了一种传感器节点自定位算
法，称为BSR（Beacons Signal Ring）定位算法，并对该算法的性能进行了评估与
比较。该算法在锚节点处的信标信号中引入能量等级的机制，无需相邻传感器节
点间信息交换，有效降低了算法复杂度与通信开销。性能分析结果显示，该算法
性能良好，在应用环境下相比于APIT算法与质心算法具有更低的位置估计误差。
论文还研究了基于双元检测传感器的协作式的目标跟踪策略，对相应的跟踪过程
进行了描述。提出了使用加权质心算法的目标位置估计模型，以及线性预测机制，
使跟踪过程具有较小的计算和通信代价。-In this thesis,we presents a buoy network of underwater GPS positioning system
model based on the wireless sensor network.The structure,function and process in the
model were analyzed.Underwater target acoustic localization algorithm were explored
through geometry way.Combined with the idea of Range-Free algorithm and distributed
algorithm,a sensor nodes self-localization algorithm were designed,which called BSR
(Beacons Signal Ring)localization algorithm,the algorithm performance evaluation and
comparison has also been presented.The algorithm use a small number of anchor nodes.
Each anchor emits beacons at different power levels.This mechanism does not required
information exchange between neighboring sensors,and reduced the complexity of the
algorithm and communication overhead effectively.The results of performance analysis
showed that BSR provides a lower position estimation error than APIT and Centroid
under a wide range of conditions.The thesis introduced process of ta Platform: |

Description: 针对基本无线传感器网络DV-Hop定位算法中，计算平均跳距时产生偏小误差的原因，提出了基于平均跳距修正的DV-Hop算法。改进算法中，引入信标节点个数比例、所有信标节点平均跳距的最大值以及所有信标节点平均跳距的平均值三个因子，并采用它们对平均跳距进行修正。通过Matlab软件对算法进行仿真验证，结果表明，改进后的 DV-Hop 算法有效降低了未知节点的定位误差，是一种可行的无线传感器网络节点定位解决方案。-DV-Hop localization algorithm for wireless sensor networks, we calculate the average hop distance small error of reasons, raised the DV-Hop algorithm based on the average hop distance correction. Improved algorithm, the proportion of the number of nodes, the introduction of beacons, the beacon node average maximum jump distance as well as all the beacon nodes average jump from the average of three factors, and their average hop distance correction. Matlab software simulation results show that the improved DV-Hop algorithm effectively reduce the unknown node positioning error, the solution is a viable wireless sensor network node positioning algorithm.
