Research On The Performance Of WLAN Based On Low Energy Withdrawal Algorithm

Battery capacity of wireless devices and energy are limited,therefore improve the performance of Wireless Local Area Network(WLAN)is becoming more and more popular,and constructing the green network became an important subject.In this article,the research of wireless local area network(WLAN)is how to reduce transmission energy consumption problems in data communication,take into account the wireless devices in the wireless channel for data communication of resignation process energy consumption.Therefore,the performance of the data communication process is improved,and the data transmission energy consumption optimization strategy is proposed to reduce the energy consumption of wireless devices and improve the performance of the wireless network.On the MAC Layer,the IEEE 802.11 MAC protocol is the current standard for wireless(point-to-point)networks.But its itself is for structural design of the wireless local area network(WLAN),and no single hop or multiple hops network performance optimization,when applied to multiple hops point-to-point wireless network,there are a lot of problems.In particular,the 802.11 MAC protocol,which uses a binary index of unfair features to perform the random withdrawal process of the avoidance algorithm,thus has many problems between different wireless network nodes.There are significant unfair problems,for example,some nodes monopolize Shared channels,while others are in "starvation mode".This paper presents the problems of retreat algorithm of IEEE802.11MAC protocol,this paper proposes a window retreat algorithm using adaptive competition,In the process of resignation to reduce collision rate and improve throughput.Based on the idea of low power consumption adaptive algorithm,the energy consumption optimization problem in WLAN node is studied.In the process of data communication,by adopting the idea of low power adaptive algorithm,to optimize the energy consumption of wireless devices,It can improve the utilization rate of energy consumption,thus extending the life cycle of wireless devices.In this paper,MATLAB simulation tool is used to simulate the model,and the two improved avoidance algorithms are compared to the throughput and collision rate,and the energy consumption is also studied.Simulation test on this algorithm and its implementation are also made.It show that the algorithm proposed in this paper,at the same time of increase network throughput,reduce energy consumption,extend the time of the survive of wireless network equipment,improve the utilization rate of energy of wireless network,stability and fairness.
