Research On Media Access Control Mechanism Of Digital Information And Energy Integrated Transmission Based On Millimeter Wave Communication

With the rapid development of mobile communication and electronic information technology,millimeter-wave communication technology has been more and more widely known,deeply studied and innovated because of its excellent wide bandwidth,narrow beam and strong detection capability.However,the research results mainly focus on multi-hop relay and spatial reuse.At the same time,these research results are independent of each other,and there is no centralized or cross-domain integrated consideration.Therefore,this thesis hopes to conduct joint analysis in the field of equipment access and discovery and energy collection sustainable communication,aiming at the extremely wide frequency band of millimeter wave band,combining with energy harvesting mechanism to ensure the sustainable work of communication systems,and to study new media access control.Firstly,according to the characteristics of millimeter-wave communication and data-energy transmission,this thesis introduces the IEEE 802.11 Mac protocol and its mechanism.At the same time,it combines the characteristics of millimeter-wave and data-energy transmission,makes a systematic modeling and theoretical description of the millimeter-wave data-energy integrated media access control mechanism,makes an abstract modeling of the application scenario and the theoretical part of the protocol mechanism.It is deduced and explained in detail.After that,the article explains the enhanced CSMA/CA protocol in indoor scene of wireless energy transmission,and finally proposes a new improved scheme for the inability of the control protocol to collect energy actively--the millimeter wave number energy integrated media access control protocol based on energy backoff interval.The protocol mechanism is introduced in detail,and the improved characteristics are described and improved.Detailed examples are given.Next,some characteristics of the energy backoff interval-based millimeter wave number energy integrated media access control protocol are explained and further improvement schemes are proposed.That is,the millimeter wave number energy integrated media access control protocol based on energy grouping is introduced in detail,its protocol mechanism is described in detail.The theoretical analysis is also carried out.And the improvement ideas of the protocol are analyzed and explained,and further improvements are made.An example is given.Next,Monte Carlo method is used to simulate and analyze the performance of two new control protocols.Detailed simulation parameter design is explained.The real effect of the protocol is verified by comparing the number of upstream throughput and STA,the ratio of upstream throughput performance to allocated time resource,the upstream throughput and the size of initial backoff window W.The simulation results show that the throughput performance of the two new protocols has been significantly improved.At the same time,the throughput of the upstream link can be maximized by allocating time resources appropriately.Millimeter-wave number-energy integrated media access control protocol based on energy grouping can be implemented more easily,and it is more energy-saving than energy backoff interval-based millimeter-wave number-energy integrated media access control protocol.Finally,this thesis summarizes the performance of MMW-Energetic Integrated Media Access Control Protocol based on energy backoff interval and MMW-Energetic Integrated Media Access Control Protocol based on energy grouping,and puts forward the future work.
