摘要: 当网络中某个节点发生故障时,为了研究该节点负荷如何分配给相连节点以维持网络的正常运行的问题,本文提出基于邻居节点最大剩余容量的负荷再分配策略.当节点出现故障时,节点的负荷需要分配给其他正常的节点,其他的节点在接收负荷的同时要考虑自身的剩余容量,避免超负荷.考虑到负荷传播过程中的能耗问题,分析了路径长度对负荷分配的影响.并通过模型网络的仿真,分析了容忍参数、负荷分配参数、路径长度对负荷分配效果的影响.结果表明,通过调节路径可调参数可使网络达到期望的效果,有效防止级联故障的传播.

Abstract: When a node in the network fails, in order to study how the node load is distributed to the connected nodes to maintain the normal operation of the network, in this paper, a load re-allocation strategy based on the maximum residual capacity of neighbor nodes was proposed. When the fault node distributes the load, the residual capacity of the receiving node was taken into account, so as to avoid the propagation of the fault caused by full load and overload after the node received the additional load. Considering the energy consumption in the process of load propagation, the influence of path length on load distribution was analyzed. Through the simulation of the model network, the influence of tolerance parameters, load distribution parameters and path length on the load distribution effect was analyzed. The results showed that the network could achieve the desired effect by adjusting the path adjustable parameters, and the propagation of cascade failure could be effectively prevented.
