为了合理高效地利用现有无线频谱资源,保障智能电网中重要控制类信息传输质量的同时,尽可能地为其他业务提供相对高质量的服务,提出了一种智能电网认知无线传感器网络基于优先级的数据分组调度机制.该机制基于差异化调度策略的思想,依据智能电力通信网流量的异构特性、业务特点和服务质量要求,为智能电力通信业务划分了优先级,进而对各个优先级设置了不同的策略,并重点考虑信道质量和信道切换造成的影响.通过Matlab软件仿真验证,基于业务优先级的数据分组调度方案有效地提高了较高优先级次级用户数据分组的传输性能,对整个系统的利用率也有所提升.
In order to reasonably and efficiently utilize the existing wireless spectrum resources and guarantee the quality of the important control information transmission in the smart grid, as far as possible to provide relatively high quality services to other services, a smart grid cognitive wireless sensor network based on the priority Level data packet scheduling mechanism based on the idea of differentiated scheduling strategy, based on heterogeneous characteristics of traffic, service features and quality requirements of intelligent power communication network, the priority for the intelligent power communication service is divided, and the priority of each priority Set different strategies and emphatically consider the impact of channel quality and channel switching.Through the simulation of Matlab software, the data packet scheduling scheme based on business priority effectively improves the transmission performance of the data packets of higher priority secondary users, The utilization of the entire system has also improved.
