The Next Generation Of Ultra-high-speed Wireless LAN Uplink Energy Efficiency Research And Simulation

Wireless LAN with its unique irreplaceable advantages becomes an important part of mobile communications. In addition, as people WLAN proposed higher rates for a variety of Qo S requirements and the needs of multimedia services, making the next generation of ultra-high-speed wireless LAN inevitably toward higher QoS guarantees and the ability to support multiple broadband develop. The subject is also to the next generation of high-speed WLAN technology(NUHT) in the context of the study.Research on wireless LAN mostly consider the allocation of resources under certain circumstances, to maximize system throughput, and for high-capacity wireless links, in order to meet the increasing demand for quality of service, the energy consumption of user devices will becomes large. However, in contrast to enhance the capacity of the battery which relative to the rate of the wireless LAN. In addition, users in the uplink transmission system power consumption dominate the wireless power budget. Accordingly, the communication network in the green, in addition to the spectral efficiency and throughput, the energy efficiency has become the mainstream trend in wireless communication.The main content of this paper is also based on the next generation of energy-efficient ultra-high-speed wireless LAN communications under. Innovative work is mainly based on the basic joint carrier aggregation(JC) and independent carrier aggregation(IC) basis, a dynamic carrier aggregation(DCA) mechanism, the system model for the uplink. In addition, due to the different application scenarios, the transmit power and system configurations and channel quality are interrelated, and each member of the component carrier(CC) of the queue length and service rate, and in order to make energy efficiency assessment more universal, the paper proposes normalized energy efficiency(NEE) indicator. The simulation analysis shows that the dynamic carrier aggregation mechanism proposed to obtain the upper limit of energy efficiency performance in an ideal balance system(IBS) next.Carrier aggregation on the dynamic mechanism for different user access bandwidth capacity, mainly refers to support carrier aggregation without affecting users, and supports carrier aggregation of user access mode hybrid system efficiency and the transmission rate to do the analysis and modeling. Proposed the use of only one primary member component carrier(PCC) of the probability assessment guidelines for energy efficiency systems, simulation results show that service the longest queue(SLQ) model to get more than a fair polling-based algorithm(RRP) for better energy efficiency.Finally, the article describes a particular class of network load model, that a load is not supported by the large amount of carrier aggregation and the user terminal. For systems more energy efficient, resource scheduler(RS) will be allocated to such users and the channel gain maximum rate of the highest members of the service carrier up. In addition, the previous mechanism proposed for DCA, but gives the upper limit of the analysis, at least, shows the data in the actual system model and the results were compared with the theoretical analysis and analysis.
