摘要
在给定的网络中,由于用户接入的随机性,容易造成网络设备的损毁或网络性能下降.首先分析合法用户与非法用户在给定网络中的接入机制,接着提出了基于非法用户随机出现和随机消亡条件下的用户接入模型.经过迭代计算用户的接入数目与设备的损毁数目,计算得到网络的连接指数.最后通过仿真验证,给出不同影响因素下用户的接入性能和连接指数变化情况.仿真结果表明,非法用户的最终接入直接影响网络连接指数,网络设备的可连接数目对连接性能的影响程度较大.
Abstract
In a given network,since the randomness of user access,it is likely to cause damage or performance degradation.In this paper,the access mechanism to the given network of users was firstly analyzed.Then a user ac-cess model was provided based on the illegal users with the properties being random appearance and extinction.Through derivative calculation of the number of user access and equipment damage,the connectivity index was calcu-lated.Finally,the access performances and connectivity index changes were demonstrated through simulation.The simulation results show that the final access of illegal user has a direct effect on connectivity index.Besides,available number has a more effect on the connection performances.
