摘要
将模糊离散事件系统(FDES)应用于车载网(VAN)的垂直切换中,综合考虑了信号强度、带宽、费用、移动速度、稳定性等因素,分别对带宽、费用和稳定性建立了模糊自动机模型,提出了垂直切换的效率函数和垂直切换模糊规则,最后举例说明了FDES在车载网垂直切换中的可行性.
Fuzzy discrete event system (FDES) was applied to the vertical handover in vehicle area network (VAN), where the factors as signal strength, bandwidth, cost, speed and stability were considered, and then fuzzy automaton model of bandwidth, cost and stability were established, and later, effectiveness function and fuzzy rules of vertical handover were proposed. At last, it was illustrated that using FDES switching was feasible in vertical network.
