MANET与Internet互联的自适应网关发现策略研究

网关发现是MANET和Internet互联的关键技术.自适应网关发现策略是在混合网关发现策略的基础上对TTL(hops)等参数动态调整以适应MANET的动态拓扑和不同网络环境的一种网关发现策略.本文指出自适应网关发现策略的关键问题是如何找到主动方法和被动方法之间的理想操作点.文章系统地介绍了目前自适应网关发现策略的研究进展,第一次给出了自适应网关发现策略的分类方法,最后结合该领域的研究现状指出自适应网关发现策略的一个发展方向,即在对TTL和advertisement interval等因素进行综合考虑的同时进一步控制Reactive Zone的范围.

Survey of Adaptive Gateway Discovery Schemes for Connecting of MANET and Internet

The gateway discovery scheme is a key problem of interconnection between MANET and Internet.Adaptive gateway discovery is based on hybrid gateway discovery,and according to dynamically adjusting TTL and other factors,adaptive schemes can fit dynamic nature and different scenarios of MANET.This paper indicates the key problem of adaptive gateway discovery schemes,which is how to select the optimal operating point between proactive and reactive strategies.The paper firstly presents a classification method aft...
