父/子微微网由于其特有的技术优势和广阔的应用前景而广受关注。文中介绍IEEE 802.15.3标准MAC协议的超帧结构和父/子微微网网络结构,提出三种新型的接入控制策略,有效解决超帧长度利用不充分、设备接入不公平、多业务QoS性能不理想等不足之处。仿真和分析结果表明,文中所提的接入控制策略可以充分利用超帧长度,有效提升网络的平均QoS满意度,保证微微网协调器、实时业务流比普通设备、非实时业务流具有更高的满意度。
Parent / child piconets have drawn much attention due to their unique technical advantages and broad application prospects. This paper introduces the IEEE 802.15.3 standard MAC protocol super-frame structure and the parent / sub-piconet network structure, proposes three new types of access control strategies to effectively address the inadequate use of super-frame length, equipment access unfair, multi-service QoS Performance is not ideal and other deficiencies. The simulation and analysis results show that the access control strategy proposed in this paper can make full use of the super-frame length, effectively improve the average QoS of the network and ensure that the piconet coordinator and real-time traffic have higher real-time traffic than normal devices and non-real-time traffic Satisfaction.
