Research of Accurate Algorithm for Mobile Sensor Network Data Based on Block Sorting Optimization Mechanism

为解决当前移动传感网部署过程中存在的传输能力较低、数据传输误差较高等不足,提出了一种基于块排序优化机制的移动传感网数据精确算法。通过簇头节点间的位置拓扑关系,构建拓扑-信号传输误差评估指标,设计了节点区域矢量评估机制,以精确追踪数据传输过程中的拓扑轨迹,并采取莫度矢量方式来降低数据传输误差,从而提升网络数据传输能力。采用块排序机制,计算排序阈值,构建了误差消除方法,从而实现间歇性簇头数据传输能力,进一步降低簇头间数据传输存在的传输误差。仿真实验表明:与当前传感领域内常用的基于能量机制的改进蚁群算法和基于节能聚类机制的覆盖图量算法相比,本算法具有更强的网络数据传输能力和更低的网络传输误差。

In order to solve the problems of low transmission capacity and high data transmission errors in the current process of mobile sensor network deployment,a precise algorithm for mobile sensor network data based on block sorting optimization mechanism is proposed,in which a topology signal transmission error evaluation index is constructed according to the topological relationship between cluster head nodes,a topological trajectory during data transmission is tracked accurately by designing a node area vector evaluation mechanism and data transmission errors are reduced by using Mordor vector method,so as to improve network data transmission capability.An error elimination method is constructed by adopting a block sorting mechanism to calculate sorting threshold value,so as to improve intermittent cluster head data transmission capability and further to reduce transmission errors between cluster heads.Simulation experiments show that compared with the commonly used improved ant colony algorithm based on energy mechanism and the coverage map quantity algorithm based on energy-saving clustering mechanism in the current sensing field,the algorithm proposed in this paper has the characteristics of strong network data transmission capability and low network transmission errors.
