摘要 结合移动Agent技术提出了一种新的基于双层卫星网络的分布式分层QoS路由算法。该算法利用移动A-gent自主地收集卫星网QoS信息,并动态地更新和维护路由表,同时采用分布式的概率路由选择策略解决了卫星网路由动态变化的问题,具有低复杂度和可扩展的特点。在NS2仿真软件下模拟了该QoS路由算法的性能。结果表明,该算法能较好地避免链路拥塞,同时具有较低的呼叫阻塞率。 A novel hierarchical and distributed QoS routing algorithm based on mobile agent for doublelayered satellite network is prestented. Mobile agents are used for collecting QoS information besides up- dating and maintaining routing table. Distributed probabilistic routing strategy sloves dynamic satellite routing problem and have the features of low complexity and scalability. The proposed QoS routing algorithm is simulated bu using NS-2 platform. Simulation results show that our algorithm can avoid link congestion and reduce the call blocking probabilities.
