摘要
提出一种改进的路由蚁群算法,算法采用了动态更新的概率替代传统的路由表,引入干扰系数作为启发信息,从而提高了算法收敛速度。通过验证,算法具有更快的收敛速度和较好的吞吐能力。在网络节点出现故障时,该算法能快速地更新节点上信息,使网络趋于平稳。
Proposes an ant colony optimization algorithm, adopts a dynamic updating probability would instead of traditional route table record, employs a interference coefficient as heuristic information to achieve high convergence speed. The experimental results show that the optimization algorithm can improve the performance of the known learning algorithms and make them converge faster. When a fault occurs ,the new algorithm can update the information of the net node quickly and stabilize network traffic.
