无线网络中分布式信号处理的能量效率:跨层分析

Energy Efficiency of Distributed Signal Processing in Wireless Networks: A Cross-Layer Analysis

Giovanni Geraci, Matthias Wildemeersch, Tony Q. S. Quek

摘要:

为了满足日益增长的移动数据需求,未来的无线网络将配备有大量的接入点(AP)。除了对能源消耗的重要影响外,致密化的趋势要求开发分散和可持续的无线电资源管理技术。了解信号处理操作的分布如何影响无线网络的能源效率至关重要。在本文中,我们提供了一个跨层的框架,以评估和比较无线网络的能量效率下的信号处理负载的不同水平的分布:(i)混合,其中的信号处理操作是共享节点和AP之间,(ii)集中,其中的信号处理是完全实现在AP,(iii)完全分布式,其中的所有操作都由节点执行。我们发现,在实际的无线网络中,混合信号处理表现出显着的能源效率增益集中和完全分布式的方法。

英文摘要:

In order to meet the growing mobile data demand, future wireless networks will be equipped with a multitude of access points (APs). Besides the important implications for the energy consumption, the trend towards densification requires the development of decentralized and sustainable radio resource management techniques. It is critically important to understand how the distribution of signal processing operations affects the energy efficiency of wireless networks. In this paper, we provide a cross-layer framework to evaluate and compare the energy efficiency of wireless networks under different levels of distribution of the signal processing load: (i) hybrid, where the signal processing operations are shared between nodes and APs, (ii) centralized, where signal processing is entirely implemented at the APs, and (iii) fully distributed, where all operations are performed by the nodes. We find that in practical wireless networks, hybrid signal processing exhibits a significant energy efficiency gain over both centralized and fully distributed approaches.
