摘要

本文以实现MANET接入Internet为应用背景,考虑到动态网关在整个网络接入过程中的重要作用,提出了一种新的适用于MANET接入Internet的动态网关的布局与选取的三层规划模型.该模型通过引入具有协调控制功能的节点(即决策节点)来对接入网络中的网关和路径的使用情况进行调控,通过上下层的交互决策协调网络整体利益和节点局部利益之间的关系,并以此作为配置网关的依据,从而优化网关布局.仿真结果表明,引入该模型后网络的延迟、开销以及吞吐率等性能指标得到了改善,验证了该模型的有效性.

Abstract

This paper,based on the application background of MANET accessing Internet,with a view to the crucial function of dynamic gateway in network accessing,proposed a new three-layer programming model for placement and selection dynamic gateways.A decision node,which has coordination control function,was introduced into the model,and was used to harmonize the utilization of gateways and routes.The three layers make decisions interactively to mediate the relationship between the network overall benefit and the node local interests.The model,as the basis of the gateway configuration,optimized the placement of the gateway.The simulation results indicate that the performance of delay,overhead and throughput has promoted after the model was introduced,which validates the validity of the model.
