移动汇聚节点无线传感器网络中的数据分发研究

发布时间：2025-06-28 01:34

　　本文的主要目的是用移动汇聚节点解决无线网络所面临的特殊挑战。本文包含对两个主要协议的四个主要贡献。第一个协议是启发式数据传播HDD(Heuristic Data Dissemination)协议,第二个协议是面向汇聚节点的树状数据传播 STDD(Sink-oriented Tree-based Data Dissemination)协议。本文对上述协议中的每个都有两个贡献,因此本文共有四个贡献。1.HDD协议HDD协议由下面两个主要部分组成,即:双环结构和HDD模型。本文对HDD协议的第一个贡献是双环结构,我们解决了汇聚节点移动性频繁更新位置的问题。此外,双环结构使传感器节点和移动汇聚节点之间的交互更加便利,因此,得以延长网络寿命。HDD协议的第二个组成部分是HDD模型,也就是本文对HDD协议的第二个贡献。HDD协议解决了数据包传输延迟的问题,尤其是从源传感器节点至移动汇聚节点的传输。HDD协议的主要思想是将整个数据路由当做一个随机过程,并在四个主要数值(方向值、传输距离、垂直距离和剩余能量)的控制下进行数据前送。本文对HDD提出了许多算法来实现此目的,与现在最先进的协议相比较,其结果也...
