一维有限区域上移动网络中干扰和中断的时间相关性

Temporal Correlation of Interference and Outage in Mobile Networks over One-Dimensional Finite Regions

Konstantinos Koufos, Carl P. Dettmann

摘要:

在实践中,无线网络部署在有限域上,移动性水平在不同位置是不同的,并且用户移动性随时间而相关。所有这些特征对干扰的时间特性都有影响,而这一点往往被忽视。在本文中,我们展示了如何将相关的用户移动性的干扰和中断相关模型。以一维有界区域上的随机航点移动模型为例,计算了其在不同位置的位移规律。在此基础上,我们说明了干扰和中断的时间相关性是位置相关的,在靠近域中心的地方较低,在那里的移动性水平高于边界附近。靠近边界,还需要更多的时间来看到不相关的干扰。我们的研究结果表明,准确描述的移动性模式是很重要的,因为它会导致更准确的理解/干扰和接收机性能建模。

英文摘要:

In practice, wireless networks are deployed over finite domains, the level of mobility is different at different locations, and user mobility is correlated over time. All these features have an impact on the temporal properties of interference which is often neglected. In this paper, we show how to incorporate correlated user mobility into the interference and outage correlation models. We use the random waypoint mobility model over a bounded one-dimensional domain as an example model inducing correlation, and we calculate its displacement law at different locations. Based on that, we illustrate that the temporal correlations of interference and outage are location-dependent, being lower close to the centre of the domain, where the level of mobility is higher than near the boundary. Close to the boundary, more time is also needed to see uncorrelated interference. Our findings suggest that an accurate description of the mobility pattern is important, because it leads to more accurate understanding/modeling of interference and receiver performance.
