基于移动代理的无线自组网络拓扑发现算法研究

摘要

With the rapid development of modern wireless network,the wireless Ad hoc network arises at the right moment. The network topology discovery technology as the core of network management plays an important role in network operation. Therefore,research of the wireless Ad hoc network topology discovery has gradually become a hot spot. An improved new idea, that is,the method of subnet division is presented based on study of the traditional topology discovery algorithm based on mobile agent. It can effectively reduce the network load on the premise of improving the topology discovery,reduce the network band⁃width,and overcome the disadvantage that convergence rate of the network topology is slow to a certain extent.%随着当代无线网络的迅猛发展，无线自组网络应运而生，而网络拓扑发现技术作为网络管理的核心，在网络运行中起着至关重要的作用，因而对无线自组网络拓扑发现的研究也逐渐成为了热点。在深入研究传统的基于移动代理的拓扑发现算法之后，给出一种改进的新思想，采用划分子网的方法，该方法可以在提高拓扑发现的基础上有效地减少网络负载，并且能够降低网络带宽，在一定程度上改善了网络拓扑收敛速度过慢的缺点。
