    摘要:

    為了對無(wú)線(xiàn)異構共存網(wǎng)絡(luò )進(jìn)行優(yōu)化并對擁塞進(jìn)行控制,通過(guò)授權輔助接入和無(wú)線(xiàn)保真對網(wǎng)絡(luò )優(yōu)化模型進(jìn)行了設計,并以馬爾科夫鏈來(lái)輔助建模。為了解決吞吐量問(wèn)題,對不同公平約束下的最大吞吐量進(jìn)行了問(wèn)題優(yōu)化,并引入了虛擬隊列來(lái)對擁塞進(jìn)行控制。實(shí)驗結果顯示,LAA-WiFi模型下共存網(wǎng)絡(luò )總吞吐量的仿真值最大值為0.99。虛擬隊列方法下吞吐量的最大值約為317,最小值約為108。LAA-WiFi模型可以對網(wǎng)絡(luò )擁塞問(wèn)題進(jìn)行緩解,且其引入的虛擬隊列方法可以對吞吐量下降問(wèn)題進(jìn)行解決。研究結果可以擴展到其他的領(lǐng)域,給不同場(chǎng)景的無(wú)線(xiàn)異構共存網(wǎng)絡(luò )的優(yōu)化和擁塞控制提供借鑒。

    Abstract:

    In order to optimize wireless heterogeneous coexistence networks and control congestion, a network optimization model was designed through authorization assisted access and wireless fidelity, and Markov chains were used to assist in modeling. In order to solve the throughput problem, the maximum throughput under different fairness constraints was optimized and virtual queues were introduced to control congestion. The experimental results show that the maximum simulation value of the total throughput of the coexisting network under the LAA-WiFi model is 0.99. The maximum throughput under the virtual queue method is approximately 317, and the minimum value is approximately 108. The LAA-WiFi model can alleviate network congestion problems, and its introduction of virtual queue methods can solve the problem of throughput degradation. The research results can be extended to other fields, providing reference for the optimization and congestion control of wireless heterogeneous coexistence networks in different scenarios.
