Ad Hoc节点移动性模型特点初探

The Basic Study of the Features of the Ad Hoc Nodes Mobility Model

无线AdHoc是一种不依赖于任何基础设施无中心自组织的多跳无线网络.对于大规模的无线网络监控,移动性一直被普遍视为制约其发展的主要障碍.作者从AdHoc网络的特点出发,研究并利用了AdHoc网络内节点的移动特性.在现实应用中,移动节点趋于显示某些相关程度(群体取向)的行为:这一特征对于改进网络产品,尤其是目前许多关于开发移动方式的项目,可以减少路由选择的开销,在大规模的移动AdHoc网络中取得良好的延展性.

The application of Ad Hoc network is gaining increasing attention with both the development of wireless communication technology and the improvement of mobile terminal. Wireless Ad Hoc network is a kind of multi-hop self-organized network not depending on any infrastructure. The modus operandi of large-scale supervising network considers mobility as the main holdback to its growth. The mobile characteristic of nodes in Ad Hoc network is proposed regarding to various perspectives, and mobility is concluded as the simulation of independent moving nodes. But actually, the moving nodes are coming to form of proximity. This character could be used for the improvement of network products, especially these who take great concern on mobility. The overhead of routing decision is reduced to a maximum extend, and also, better scalability is achieved at the same time.
