摘　　要：静态路由模拟策略中大规模网络的时间复杂度和空间复杂度较大,严重阻碍网络模拟应用,为解决这个问题,提出了一种简化的NS2路由模拟策略。该策略通过对静态路由模拟策略中的节点进行分类,使路由计算时只有路由器节点参与;地址分类器设置时,终端节点有选择的参与。实验结果表明,该策略在不影响模拟真实性的前提下,有效地降低了时间开销与存储开销,更适合大规模网络环境下复杂应用的模拟。To solve the problem of the static routing strategy large complexity in time and space that often occurs in large-scale network simulation, which hinders the application of network simulation seriously, a NS2 simulation strategy is proposed to simplify routing. This strategy classifies the nodes ofstatic routing strategy. Only the router nodes participate in the calculation routing. When the method sets address classifier, the terminal nodes participate in it selectively. Experiments show that the proposed strategy can not only decrease the consumption in time and space effectively on the premise of not affecting the authenticity of simulation but also is more suitable for large-scale network simulation of complex application environments.
