Udo Schilcher, Jorge F. Schmidt, Christian Bettstetter

摘要:

深入了解无线网络中干扰的时间动态对于通信协议、调度和干扰管理的设计至关重要。本文应用随机几何调查干扰动态的第一次在网络中的节点,使用载波侦听多址接入。这种类型的网络近似的Matérn硬核点过程的类型II与Nakagami衰落。我们推导和分析表达式的方差,协方差和相关的干扰功率在空间中的一个给定的点。结果表明,即使常用的泊松近似载波侦听多址接入可能有相同的平均干扰比Matérn模型,三个干扰动态测量研究表现显着不同。

英文摘要:

A thorough understanding of the temporal dynamics of interference in wireless networks is crucial for the design of communication protocols, scheduling, and interference management. This paper applies stochastic geometry to investigate interference dynamics for the first time in a network with nodes that use carrier sense multiple access. This type of networks is approximated by a Matérn hard-core point process of type II with Nakagami fading. We derive and analyze expressions for the variance, covariance, and correlation of the interference power at a given point in space. Results show that even though the commonly used Poisson approximation to carrier sense multiple access may have the same average interference than the Matérn model, the three interference dynamics measurements investigated behave significantly different.
