基于虚拟MAC的电力线载波与无线融合及业务分配策略研究

Research on Virtual MAC-based Power Lines and Wireless Communication Network Fusion and Traffic Allocation Strategy

随着配电物联网营配贯通、IP化等需求的提出,单一电力线载波、无线等通信技术的性能已难以满足应用需求。两种技术的深度融合和协同可实现优势互补,解决单一技术业务承载能力差等问题。为此该研究基于虚拟MAC的电力线载波与无线融合技术,提出一种链路选择与业务分配策略。基于排队论对虚拟MAC层在单跳网络与多跳网络中的业务分配方案进行建模分析,以减小时延为优化目标,根据网络参数,确定各链路业务分配比例。数值分析表明,所提出的业务分配策略能够减小通信系统的时延。

To meet the increasing demands of marketing and distribution fusion and IP distribution in internet of things,it is difficult for a single power line or wireless communication technology to meet all the services requirements.The cooperation of power line and wireless communication can complement each other,and thus to solve the problems of poor supporting capability of a single technology.Consequently,we studied the power line and wireless network fusion based on virtual MAC,and proposed a link selection and traffic allocation strategy.Based on the queuing theory,the traffic allocation scheme of the virtual MAC layer both in single-hop network and multi-hop network were modeled and analyzed,where the delay is taken as the optimization target,and the traffic allocation proportion of each link is determined according to the network parameters.Numerical analysis shows that the proposed traffic allocation strategy can reduce the communication delay.
