【摘要】 移动自组网(MANET)的节点要进行Internet连接,就必须寻找Internet网关。如何寻找和维持与Internet网关的连接是这个问题的关键,再者,就是如何切换到一个更合适的相邻网关。MANET节点接入Internet有两种不同方式,即单一固定网关和多网关模式。文中提出动态网关的体系结构及适应此结构的路由协议(ADHR),动态网关作为MANET和Internet之间的接口起桥梁作用。仿真结果显示,ADHR路由协议更适合动态网关体系结构下的自组网与Internet互联。更多还原

【Abstract】 In order for an ad hoc networks mobile host to possess Internet connectivity,it must be able to find an Internet gateway.This issue consists of how to find and maintain contact with Internet by gateway.Additionally,how to handover to a more suitable neighboring gateway is also related to this issue.There are two different kinds of accessing modes,i.e.,single fixed gateway and multi-gateway.In this paper,dynamic gateway architecture and routing protocol(ADHR) are proposed,which acts as an interface between MANET and the Internet.Our simulation results show that ADHR routing protocol is appropriate for the dynamic gateways architecture of ad hoc Internet connectivity.更多还原
