摘要
本文在分析现有自适应蚁群算法局限性的基础上,提出了一种基于时延的自适应多QoS路由算法,它在满足带宽和时延波动约束条件下,直接利用前一周期的时延信息来更新路由表,以作为当前寻找路径的依据。仿真和分析结果表明,该算法具有快速准确的特点,能够及时协调网络拥塞和资源有效利用两者间的矛盾。
A new fast adaptive routing algorithm to overcome the drawbacks of adaptive ant-based control algorithm is proposed. The network delay information is introduced to update routing table to avoid congestion and to utilize network resources effectively with multiple QoS constraints. Simulation results show that the algorithm is effective and simple.
