Study On Resource Allocation And QoS Optimization Based On Wireless Mesh Network

Wireless Mesh Network(WMN)is a kind of distributed new network technology that supports multi-hop mesh packet routing and forwarding and has high capacity and high speed.Compared with traditional Ad hoc networks and wireless local area networks(WLANs),WMNs have unique features and advantages,such as higher reliability,higher data throughput,and less interference to others.However,WMN is affected by many factors such as signal attenuation and interference.Therefore,in view of these problems,this paper studies how to implement WMN network resource allocation from the three aspects of wireless routing technology,wireless channel allocation mechanism and wireless power control algorithm.How to optimize QoS parameters to meet the needs of different services or users?QoS requirements.The main research work of this paper is as follows:(1)This paper aims at the characteristics of wireless mesh networks,using cross-layer technology to study WMN resource allocation and QoS optimization.By studying the key technologies of WMN QoS optimization,the current research status of existing technologies is introduced,and the advantages and disadvantages of these technologies are summarized.Based on this,a new routing metric is proposed.Based on this routing metric,a new routing protocol is designed.Increased network throughput and reduced transmission delays.Experimental results show that the proposed routing protocol is at a higher level regardless of the load or channel difference.(2)Considering the allocation of wireless channels,according to the characteristics of WMN,according to the characteristics of WMN,a fixed channel transform algorithm is proposed based on the wireless channel allocation mechanism.The wireless network resources can be reasonably allocated in today's unpredictable wireless channels,improving network performance and system efficiency.The experimental results prove the effectiveness,convergence and superiority of the algorithm.(3)Based on game theory and queuing analysis theory,by analyzing the advantages and disadvantages of existing power control algorithms,a power control technology based on game theory for layered structure WMN is designed,and mathematical analysis and experiments are performed.Actually proved the effectiveness and superiority of the algorithm.
