摘要
在研究标准蚁群优化算法的基础上,提出一种旨在改善网络路由的蚁群优化算法以应用于云环境下多元化复杂的网络结构环境。新算法在原有蚁群算法智能寻优的基础上,加入网络节点在网审查机制,实时判断网络节点是否在网,选择最优解路径。仿真实验表明,改进算法能有效地改善因为网络节点在网情况的多变性而造成的部分路径失效的情况,进而缓解网络拥塞。
Based on the research of the original colony optimization algorithm,an improved ant colony optimization algorithm is proposed to improve the network routing quality for the colud environment which has more complex network structure.The new algorithm adopts an network node review mechanism which can judge whether the network node is online or not in real time,and get the optimal solution network routing path.Simulation results show that the improved algorithm can effectively improve the network routing quality when partial network path has no effect caused by the variability of the network nodes in the network,so as to solve some network congestion problems.
