【摘要】:車聯(lián)網(wǎng)是移動互聯(lián)網(wǎng)的延伸,其中基站協(xié)作的D2D通信適用于車間交通消息的短距離無線傳播。針對車輛快速移動導(dǎo)致的通信鏈路動態(tài)性,提出了一種基于可變距離的D2D連接選擇方法。通過選擇行車道及車間距離參數(shù),估計D2D連接對的信道質(zhì)量,推導(dǎo)了D2D連接選擇的優(yōu)先指數(shù),并基于該優(yōu)先指數(shù)建立D2D通信鏈路進行交通消息傳播。仿真結(jié)果顯示,所提方法在D2D連接的生存時間、傳輸效率方面得到提高,同時降低了D2D通信的中斷概率,提升了車輛間通信可靠性。
[Abstract]:Vehicle networking is an extension of mobile Internet, in which D2D communication based on base station cooperation is suitable for short distance wireless transmission of workshop traffic message. A D2D connection selection method based on variable distance is proposed for the dynamic communication link caused by the rapid movement of vehicle. The channel quality of D2D connection pair is estimated by selecting lane and workshop distance parameters, and the priority index of D2D connection selection is derived. Based on this priority index, D2D communication link is established for traffic message transmission. The simulation results show that the proposed method can improve the lifetime and transmission efficiency of D2D connection, reduce the outage probability of D2D communication, and improve the reliability of inter-vehicle communication.
