Random Access with Opportunity Detection in Wireless Networks

Jinho Choi, Seung-Woo Ko, Koji Yamamoto, Seong-Lyun Kim

摘要:

这封信提出了一种新的随机媒体访问控制(MAC)的基础上的传输机会预测,这可以测量的形式,给定的发射机侧干扰的条件成功概率。传输概率取决于机会预测,防止不加选择的传输并减少导致冲突的过度干扰。使用随机几何,我们推导出一个不动点方程,以提供最佳的传输概率最大化成比例公平的吞吐量。其近似解以封闭形式给出。建议的MAC是适用于全双工网络,导致显着的吞吐量提高,允许更多的节点进行传输。

英文摘要:

This letter proposes a novel random medium access control (MAC) based on a transmission opportunity prediction, which can be measured in a form of a conditional success probability given transmitter-side interference. A transmission probability depends on the opportunity prediction, preventing indiscriminate transmissions and reducing excessive interference causing collisions. Using stochastic geometry, we derive a fixed-point equation to provide the optimal transmission probability maximizing a proportionally fair throughput. Its approximated solution is given in closed form. The proposed MAC is applicable to full-duplex networks, leading to significant throughput improvement by allowing more nodes to transmit.
