摘　　要：针对当前算法网络平均时延高、负载率低等问题,提出基于蚁群算法的容迟网络多通道协作路由跨层控制算法。建立概率转移矩阵,完成容迟网络链路容量的离散化分析,并利用网络节点转发的探测包来探索路由的情况,通过转发和复制两种方式分析,给出数据包的转发策略,确定网络中数据包的转发情况。利用转发策略来帮助路由跨层控制,达到维护路由的目的。在此基础上,分别计算网络的延迟约束、宽带约束、延迟抖动约束和包丢失率约束条件的目标函数值,实现了容迟网络多通道协作路由跨层控制。实验结果表明,提出算法的网络平均时延较低、负载率较高,并且能够准确的控制网络,验证了提出算法的有效性。Due to high average delay and low load rate of traditional methods,this article put forward an algorithm of multi-channel cooperative routing cross-layer control in delay tolerant network based on ant colony algorithm.Firstly,the probabilistic transfer matrix was established to analyze the capacity of delay-tolerant network link.Secondly,the network node forwarding explorer packet was used to explore the routing.By the way of forwarding and copying,the forwarding strategy of data packet was given and the forwarding situation of data packet in the network was determined.The forwarding strategy was used to help the cross-layer routing control,so as to maintain the route.On this basis,objective function values of delay constraints,wideband constraints,delay jitter constraints and packet loss constraints were calculated respectively.Thus,multi-channel cooperative routing cross-layer control in delay-tolerant network was achieved.Simulation results show that the proposed algorithm has the advantages of low average network delay,high load rate.Meanwhile,this algorithm can control the network accurately.Thus,the effectiveness of the proposed algorithm is proved.
