摘　　要：给出一种基于Vague集的异构网络垂直切换算法,在模糊化时将参数映射到Vague集上,并构造新的计分函数使其更为智能化。仿真结果表明,所给算法可减少不必要切换的频率,减小乒乓效应的不利影响。A vertical handoff algorithm for heterogeneous networks based on vague set is presented.The parameters are mapped to vague set in fuzzy time,and a new score function is constructed to make it more intelligent.Simulation results show that,the proposed algorithm can reduce the frequency of unnecessary switching,and narrow the adverse side of Ping-pong effect.
