一种基于MPLS的Ad hoc无线移动网络解决方案

A solution to Ad hoc networks based on MPLS

为改善目前Ad hoc网络在服务质量和流量工程支持上的不足,提出了一种节点独立多径的Ad hoc标签交换按需路由协议（AODLS）和基于多协议标签交换（MPLS）的Ad hoc无线移动网络模型。该协议通过将Ad hoc网络的路由技术与MPLS的标签快速交换技术相结合,使Ad hoc网络不仅能够支持传统的、无连接的IP服务,还能应用于移动MPLS网络,使其具备MPLS的服务质量（QoS）保证和流量工程的优点。仿真结果表明,AODLS在吞吐量、时延及路由发起频率上均比AODV路由协议有所改善,在节点移动情况下更加明显。

In order to solve the lack of quality of service （QoS） and traffic engineering in Ad hoc, an Ad hoc wireless network model based on multi-protocol label switching （MPLS） and a node disjoint multipath Ad hoc on-demand label switching muting protocol （AODLS） were proposed. Through combining the muting techniques in Ad hoc with the label fast-forwarding techniques in MPLS, the traffic engineering, QoS function and fast forwarding ability were provided. It makes the Ad hoc can support the conventional service with IP-forwarding and can adapt to the mobile MPLS network. Simulation results show that AODLS is better than AODV in ways of average lower end to end delay, mute discovery frequency and network throughout, especially in mobile situation.
