摘要
电力线通信(PLC)采用电力系统的电力线作为通信媒介,因此其方便性无与伦比。同时,它被认为是智能电网中最好的通信技术之一。这种技术必然在未来得到越来越广泛的应用。然而,系统的时间变化也将导致减少信道利用率。文中提出了一种基于PRIME的混合信道分配方法。它结合了TDMA和CSMA/CA的优势,使用分时传输的思想,可以显着避免碰撞,提高吞吐量并减少传输延迟。仿真结果表明该方法是可行和有效的。该方法对提高PLC的整体性能具有重要意义。
Power line communication(PLC)uses the power line of the power system as the communication medium,so its convenience is unmatched.At the same time,it is considered one of the best communications technologies in the smart grid.This kind of technology must be applied more and more widely in the future.However,the PLC's entire network shares one channel,resulting in insufficient channel resources.Changes in the time of the PLC system will also lead to reduced channel utilization.This paper proposes a PRIME-based hybrid channel allocation method.It combines the advantages of TDMA and CSMA/CA.Using the idea of time-sharing transmission,it can significantly avoid collisions,improve throughput and reduce transmission delay.Simulation results show that this method is feasible and effective.This method is of great significance to improving the overall performance of the PLC.
