Many have proposed to connect Mobile Ad Hoc Networks (MANETs) to a wired backbone Internet access network. This paper demonstrates that a wired backbone network can be utilized for more than just providing access to the global Internet. Traffic between mobile nodes in the ad hoc network may also be routed via this backbone network to achieve higher throughput, and to reduce the load in the ad hoc network. This is referred to as transit routing. This paper proposes a cost metric algorithm that facilitates transit routing for some of the traffic flows between nodes in the MANET. The algorithm aims at carrying out transit routing for a flow only when it leads to improvements of the performance. The proposal is implemented and tested in the ns-2 network simulator, and the simulation results are promising.

内部MANET通信在外部网络上的路由

许多人提议将移动自组织网络（MANET）连接到有线骨干网Internet访问网络。本文演示了有线骨干网不仅仅可以提供对全球Internet的访问，还可以用于更多用途。ad hoc网络中的移动节点之间的流量也可以通过此骨干网络进行路由，以实现更高的吞吐量，并减少ad hoc网络中的负载。这称为转接路由。本文提出了一种成本度量算法，该算法可简化MANET节点之间某些流量的转接路由。该算法旨在仅在导致性能提高时才对流执行转接路由。该方案在ns-2网络模拟器中进行了实施和测试，仿真结果是有希望的。
