IEEE802 .11移动IPv6网络中基于模糊逻辑趋势的智能切换

Smart handover based on fuzzy logic trend in IEEE802.11 mobile IPv6 networks

Joanne Mun-Yee Lim, Chee-Onn Chow

摘要:

一个适当设计的切换算法是必不可少的,在减少连接质量恶化时,移动节点移动跨越小区边界。因此,为了提高通信质量,我们在本文中确定了三个目标。第一个目标是通过使用附加参数来减少由于多径和阴影效应引起的RSSI读数的误报,从而最大限度地减少不必要的干扰并提高通信质量。第二个目标是通过利用位置因素作为模糊逻辑切换算法中的输入参数之一,根据用户的移动性来控制切换决策。第三个目标是通过在做出切换决定之前监视模糊逻辑输出的趋势一段时间来最小化由参数的突然波动引起的误切换警报。本文采用模糊逻辑,以RSSI、速度和距离作为切换触发算法的输入判决准则。在切换被触发之前,模糊逻辑输出趋势被监视一段时间。最后,通过仿真,我们证明了所提出的切换算法在实现更好的通信质量的有效性。

英文摘要:

A properly designed handoff algorithm is essential in reducing the connection quality deterioration when a mobile node moves across the cell boundaries. Therefore, to improve communication quality, we identified three goals in our paper. The first goal is to minimize unnecessary handovers and increase communication quality by reducing misrepresentations of RSSI readings due to multipath and shadow effect with the use of additional parameters. The second goal is to control the handover decisions depending on the users' mobility by utilizing location factors as one of the input parameters in a fuzzy logic handover algorithm. The third goal is to minimize false handover alarms caused by sudden fluctuations of parameters by monitoring the trend of fuzzy logic outputs for a period of time before making handover decision. In this paper, we use RSSI, speed and distance as the input decision criteria of a handover trigger algorithm by means of fuzzy logic. The fuzzy logic output trend is monitored for a period of time before handover is triggered. Finally, through simulations, we show the effectiveness of the proposed handover algorithm in achieving better communication quality.
