| 摘 要： | 在Ad Hoc接入网中，Ad Hoc节点通过外地代理与骨干网中的对等节点通信。外地代理的选择算法是影响Ad Hoc接入网整体性能的主要因素之一。针对Jelger算法存在切换频繁和平均跳数较大的缺点，该文提出了一种基于跳数和路由稳定度的改进算法。相对于Jelger算法，改进的算法可以减少切换次数和移动节点到外地代理的平均跳数，同时具有更小且更加稳定的丢包率。

| Abstract: | In Ad Hoc access networks,Ad Hoc nodes communicate with the correspondent nodes in the backbone networks via the foreign agent.One of the key components affecting the overall performance of Ad Hoc access networks is the algorithm used to select foreign agents.Since Jelger algorithm has the defect of frequent handoffs and more average hops,an improved algorithm based on hops and route stability is proposed.Compared with Jelger algorithm,the proposed algorithm can remarkably decrease the handoff times and average hops to the foreign agents.Additionally,it has lower and more stable packets lost ratio. |

| Keywords: | Ad Hoc access networks foreign agents Jelger algorithm routing stability |
