摘要:

在本文中,我们进行了深入的分析,树算法与多包接收(MPR)和连续干扰消除(SIC),显示了一些新的结果。我们首先推导出的基本性能参数,这是预期的冲突解决间隔的长度和归一化的吞吐量,条件的竞争用户的数量。然后,我们研究他们的渐近行为,确定一个振荡的组成部分,放大与MPR的增加。在接下来的步骤中,我们推导出吞吐量的门控和窗口访问,假设泊松到达。我们发现,对于窗口访问,最大稳定的归一化吞吐量的界限随着MPR的增加而增加。这意味着投资于先进的身体能力,即,MPR和SIC从媒体访问控制算法的角度来看是值得的。

英文摘要:

In this paper, we perform a thorough analysis of tree-algorithms with multi-packet reception (MPR) and successive interference cancellation (SIC), showing a number of novel results. We first derive the basic performance parameters, which are the expected length of the collision resolution interval and the normalized throughput, conditioned on the number of contending users. We then study their asymptotic behaviour, identifying an oscillatory component that amplifies with the increase in MPR. In the next step, we derive the throughput for the gated and windowed access, assuming Poisson arrivals. We show that for windowed access, the bound on maximum stable normalized throughput increases with the increase in MPR. his implies that investing in advanced physical capabilities, i.e., MPR and SIC pays off from the perspective of the medium access control algorithm.
