【摘要】：对室内VLC-WiFi异构网络进行研究,提出了基本的组网结构及改进的切换策略。根据室内VLC-WiFi异构网络的特点,确定了上下行传输方案,即上行数据使用WiFi链路传输,下行数据使用VLC和WiFi链路传输。当下行VLC链路不可用时,提出了一种基于切换间隔和运动趋势的动态驻留时间算法。仿真结果表明,提出的切换算法与传统算法相比,在不增加乒乓效应的前提下提高了系统的命中率。
[Abstract]:Based on the research of indoor VLC-WiFi heterogeneous network, the basic network structure and improved handoff strategy are proposed. According to the characteristics of indoor VLC-WiFi heterogeneous network, the uplink data is transmitted by WiFi link and the downlink data is transmitted by VLC and WiFi link. When downlink VLC link is unavailable, a dynamic dwell time algorithm based on handoff interval and motion trend is proposed. Simulation results show that the proposed switching algorithm improves the hit ratio of the system without increasing ping-pong effect compared with the traditional algorithm.
