【摘要】:對室內(nèi)VLC-WiFi異構(gòu)網(wǎng)絡(luò)進(jìn)行研究,提出了基本的組網(wǎng)結(jié)構(gòu)及改進(jìn)的切換策略。根據(jù)室內(nèi)VLC-WiFi異構(gòu)網(wǎng)絡(luò)的特點(diǎn),確定了上下行傳輸方案,即上行數(shù)據(jù)使用WiFi鏈路傳輸,下行數(shù)據(jù)使用VLC和WiFi鏈路傳輸。當(dāng)下行VLC鏈路不可用時(shí),提出了一種基于切換間隔和運(yùn)動趨勢的動態(tài)駐留時(shí)間算法。仿真結(jié)果表明,提出的切換算法與傳統(tǒng)算法相比,在不增加乒乓效應(yīng)的前提下提高了系統(tǒng)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.
