摘　　要：针对软件定义无线网络(SDWN)中接入点密集部署场景中的切换问题,从用户侧角度提出基于移动方向预测的SDWN无缝切换方案.该方案引入路径向量,综合考量信号强度值、接入点负载和路径向量等参数在切换中的作用,重新构造SDWN网络中切换权重因子,为用户选择最优的无线接入点.通过开源平台Mininet-WiFi仿真对比,证明该方案可以有效减少不必要的切换,提升用户体验.Aiming at the handover problem in the dense deployment scenario of access points in software defined wireless networking(SDWN),a seamless handover solution based on moving direction prediction SDWN is proposed,which considers much more user's sake.Based on the comprehensive consideration of signal strength value,access point load and path vector and other parameters,this solution reconstructs SDWN the handoff weight factor to select the optimal wireless access point for users.Through the simulation and comparison of the Mininet-WiFi,it is proved that the scheme can effectively reduce unnecessary switching and improve user's experience.
