Adaptive Multi-hop Access Routing Protocol in NGN Heterogeneous Networks
首发时间:2005-01-06
Abstract:he next generation networks will be an all IPv6 based network and composed of diverse wired and wireless radio access technologies. The signals received by mobile terminals may come from different networks. How to select the best network suitable to current traffic is the key issue of guaranteeing the service of quality in heterogeneous networks. The traditional single-hop access method used in 3G/2.5G cellular network will inevitably cause the base station as a communication bottleneck. MANET utilizes the dynamic multi-hop routing method. Mobile nodes in ad hoc network are also as routers, which increase the power consuming of mobile nodes. An adaptive multi-hop access routing protocol is newly presented in this paper. It combines the single hop character used in conversional cellular networks with the self-organization in ad hoc networks. When quality of service of the network access points cannot satisfy the service demands, the mobile terminals can transfer packets with the hel

NGN异构环境下的自适应多跳接入路由协议
摘要:下一代网络将由不同的有线和无线网络组成,在某区域内移动用户可能接收到来自不同网络的信号。如何为漫游用户选择适应当前业务的最佳网络接入是保证业务在异构环境下实现高质量通信的关键问题。3G/2.5G蜂窝网采用传统的单跳接入方式,移动用户通过小区基站接入骨干网,这样小区基站不可避免地将会成为通信的瓶颈。而MANET网采用动态多跳选路方式,节点也作为路由器为其他节点转发数据,但却增大了节点的功耗。本文将蜂窝网的单跳接入和ad hoc网的多跳路由结合起来,提出一种自适应的多跳接入方式。当移动节点发现网络接入点的服务质量不能满足业务要求时,通过周围节点以多跳方式接入,从而保证通信业务的QoS并能提高网络的吞吐量。同时,该协议具有多跳路由功能,当源点与目的点移动到同一小区时,在小区内实现ad hoc方式的动态路由,而无须经过小区基站,从而减少了基站负荷,提高了网络性能
