摘要:

无线光通信是一种很有前途的水下宽带接入网络技术,在高分辨率环境监测应用中尤为重要。介绍了一种基于无线光网络的深海监测系统。我们将这样的光无线网络建模为一般的中继网络,并建立了一个最优中继放置问题,其目标是最大化整个系统的稳定区域,即,网络能够容纳的通信量的上确界。公式化的优化问题进一步被证明是非凸的,因此它的全局优化是非平凡的。在本文中,我们开发了一个全局优化方法,这个问题,我们提供了一个有效的算法来计算最优解。通过数值计算,我们表明,一个显着的性能增益可以通过使用导出的最优解。

英文摘要:

Optical wireless communication is a promising technology for underwater broadband access networks, which are particularly important for high-resolution environmental monitoring applications. This paper focuses on a deep sea monitoring system, where an underwater optical wireless network is deployed on the seafloor. We model such an optical wireless network as a general queueing network and formulate an optimal relay placement problem, whose objective is to maximize the stability region of the whole system, i.e., the supremum of the traffic volume that the network is capable of accommodating. The formulated optimization problem is further shown to be non-convex, so that its global optimization is non-trivial. In this paper, we develop a global optimization method for this problem and we provide an efficient algorithm to compute an optimal solution. Through numerical evaluations, we show that a significant performance gain can be obtained by using the derived optimal solution.
