基于定向扩散路由的结构化分层模型

Structured Hierarchical Model Based on Directed Diffusion

在无线传感网中,定向扩散协议(Directed Diffusion,DD)提供了一个基于平面拓扑的以数据为中心的路由思想。针对基于应用的无线传感网络,许多研究人员对DD进行了相应的改进,但是都缺乏一个统一清晰的架构。为了提高研究和开发效率,文中通过科学研究和系统归纳提出了一个基于DD的结构化分层模型,力图呈现一个基于DD的清晰、完整的体系架构,在此模型的启发下,提出了能量多路径加强的DD协议。最后通过性能分析证明了改进算法的可行性,同时也给出了此模型的一个有效应用。

In wireless sensor networks, Directed Diffusion Protocol （DD） provides a fiat topology based data-centric muting thought. Based on the application of wireless sensor networks,many researchers make corresponding improvement of DD,but lack of a unified and clear structure still unsolved. In order to improve the efficiency of research and development, through scientific research and systematic summarizing,present a DD structure-based hierarchical model seeks to provide DD in a clear,complete system architecture,and inspired by this model, proposed the energy multipath strengthening DD. Finally, the performance analysis proves the feasibility of the improved algorithm,also gives an effective application of this model.
