Neste artigo, é apresentada uma análise de geometria estocástica da configuração inversamente proporcional (IPS) do limiar de detecção de portadora (CST) e da potência de transmissão para redes locais sem fio (WLANs) densamente implantadas. Em WLANs densamente implantadas, o ajuste de CST é uma tecnologia crucial para melhorar a reutilização espacial, mas pode privar os transmissores circundantes devido a uma relação assimétrica de detecção de portadora. Para que a relação de detecção da portadora seja simétrica, o IPS do CST e a potência de transmissão é uma abordagem promissora, ou seja, cada transmissor ajusta conjuntamente seu CST e potência de transmissão para que seu produto seja igual ao dos demais. Esta configuração é usada para reutilização espacial no IEEE 802.11ax. Assumindo que o conjunto de transmissores potenciais segue um processo de ponto de Poisson, o impacto do IPS no throughput é formulado com base na geometria estocástica em dois cenários: um ajuste em um único transmissor e um ajuste idêntico em todos os transmissores. A expressão assintótica do rendimento em WLANs densas é derivada e uma solução explícita do CST ideal é alcançada como uma função do número de transmissores potenciais vizinhos e da relação sinal-interferência de potência usando aproximações. Esta solução foi confirmada através de resultados numéricos, onde a solução explícita obteve penalidades de rendimento inferiores a 8% em relação à solução ótima avaliada numericamente.

Abstract: In this paper, a stochasic geometry analysis of the inversely proportional setting (IPS) of carrier sense threshold (CST) and transmission power for densely deployed wireless local area networks (WLANs) is presented. In densely deployed WLANs, CST adjustment is a crucial technology to enhance spatial reuse, but it can starve surrounding transmitters due to an asymmetric carrier sensing relationship. In order for the carrier sensing relationship to be symmetric, the IPS of the CST and transmission power is a promising approach, i.e., each transmitter jointly adjusts its CST and transmission power in order for their product to be equal to those of others. This setting is used for spatial reuse in IEEE 802.11ax. By assuming that the set of potential transmitters follows a Poisson point process, the impact of the IPS on throughput is formulated based on stochastic geometry in two scenarios: an adjustment at a single transmitter and an identical adjustment at all transmitters. The asymptotic expression of the throughput in dense WLANs is derived and an explicit solution of the optimal CST is achieved as a function of the number of neighboring potential transmitters and signal-to-interference power ratio using approximations. This solution was confirmed through numerical results, where the explicit solution achieved throughput penalties of less than 8% relative to the numerically evaluated optimal solution.
