在含权无标度网络中,路由策略对网络的整体性能有着重大的影响,为提高网络的吞吐量,兼顾较低的信息包平均传输时延,提出一种混合路由算法.为有效利用全局信息,以路径上的节点强度连乘积定义有效代价,通过信息包队列长度的动态信息来增强算法的适应性;为保证实时根据网络中节点的拥塞程度调整路由选择,利用信息包队列长度与发送能力之间的关系自适应调整邻居节点权值,以达到在网络中平均分布信息包.在不同节点发送能力环境下的仿真实验表明了所提混合路由算法的有效性.
In the weighted scale-free network, the routing strategy has a significant impact on the overall network performance. In order to improve the throughput of the network and take into account the lower average packet transmission delay, a hybrid routing algorithm is proposed. In order to effectively use the global Information to the node strength on the path of the product of the effective cost of the definition of the length of the packet queue through the dynamic information to enhance the adaptability of the algorithm; in order to ensure real-time node in the network to adjust the degree of congestion routing, the use of packet queue length and send The relationship between capabilities adaptively adjusts the weights of neighboring nodes to achieve the average distribution of packets in the network.A simulation experiment under different nodes’ sending capabilities shows the effectiveness of the proposed hybrid routing algorithm.
