车路通信环境下TD-LTE无线资源调度建模与仿真
Research on resource scheduling algorithm in V2I communication access system based on TD-LTE
摘要
Abstract
To improve the existing V2I communication mode with small-scale coverage,long delivery latency and low trans-mission rate,TD-LTE technology was introduced into V2I communication access system. A radio resource scheduling model based on TD-LTE is proposed for V2I communication access system. Three typical resource scheduling algorithms of PF,EXP and M-LWDF were tested and contrasted in different vehicle mobile simulation scenarios. Simulation results show that in slow moving scenario,when the system load is low,EXP algorithm can provide better performance;M-LWDF algorithm can perform better as load is enhenced;PF algorithm is not suitable for multi-media resource scheduling. In high moving scenario,all the three algorithms are not suitable.关键词
