水声通信网络的资源分配发展综述

Development Overview of Resource Allocation in Underwater Acoustic Communication Networks

摘要:

随着陆地资源的枯竭，人类逐渐把目光转向了蓝色海洋。水声通信网络(Underwater Acoustic Communication Network，UACN)能够有效实现水下信息交互，是认识、开发、利用海洋的重要工具，并在推动“智慧海洋”建设中发挥着重要作用。但是，水下节点的发射功率、转发中继、通信信道等通信资源严重受限，这将无法满足 UACN 长期且有效作业的需求。资源分配技术能够在不提升网络硬件成本的情况下有效改善网络能量效率、抗干扰性等相关性能，在水下信息交互需求激增的背景下具有极高的研究意义与应用价值。因此，如何对有限的网络资源进行合理分配已成为 UACN 领域的研究热点之一。首先对 UACN 系统进行了简要介绍，然后研究分析了 UACN 资源分配技术及意义，并重点指出了其资源分配的发展现状、趋势和面临的挑战。

Abstract:

As land resources have been depleted，the blue ocean has attracted extensive attention. Underwater acoustic communication network(UACN)can effectively achieve underwater information interaction. It is an important tool for understanding，developing and utilizing the ocean，and plays an important role in promoting the construction of smart ocean. However，the severe constraints of network communication resources(e.g.，transmission energy，relay，communication channel)will lead to a failure to meet the long-term and effective operation requirements of UACN. Without increasing the cost of network hardware，the resource allocation technology can effectively improve network performances such as energy efficiency and anti-interference. It is of great research significance and application value under the background of rapidly increasing demand for underwater information interaction. Therefore，the proper resource allocation for limited network resource has gradually become a research hotspot in the field of UACN. In this paper，the UACN system was firstly introduced，and then the technology and significance of UACN resource allocation were discussed. Finally，the development status，trend and challenges of UACN resource allocation were put forward.
