无线移动网络和设备变得越来越流行，为用户提供随时随地的访问。我们现在目睹了对无线网络支持数据和实时多媒体流量的前所未有的需求。无线移动系统基于蜂窝方法，并且该区域由彼此重叠的小区覆盖。在移动蜂窝系统中，切换是一个非常重要的过程。文献中提出了许多切换算法。然而，在无线网络中实现更好的切换并保持QoS是非常困难的任务。因此，应该实施新的智能算法来处理这个问题。在本文中，我们对两种基于模糊逻辑的切换系统进行了比较研究。我们实现了两个基于模糊的切换系统 (FBHS)，称为 FBHS1 和 FBHS2。通过仿真进行的性能评估表明，FBHS2 比 FBHS1 具有更好的行为，并且在所有仿真情况下都可以避免乒乓效应。
Wireless mobile networks and devices are becoming increasingly popular to provide users the access anytime and anywhere. We are witnessing now an unprecedented demand for wireless networks to support both data and real-time multimedia traffic. The wireless mobile systems are based on cellular approach and the area is covered by cells that overlap each other. In mobile cellular systems the handover is a very important process. Many handover algorithms are proposed in the literature. However, to make a better handover and keep the QoS in wireless networks is very difficult task. For this reason, new intelligent algorithms should be implemented to deal with this problem. In this paper, we carried out a comparison study of two handover systems based on fuzzy logic. We implement two Fuzzy-Based Handover Systems (FBHS) called FBHS1 and FBHS2. The performance evaluation via simulations shows that FBHS2 has better behavior than FBHS1 and can avoid ping-pong effect in all simulation cases.
