Abstract

Three main kinds of underwater wireless communication, which employ acoustic waves, radio frequency and optical waves, have attracted intensive research interests in recently years. Among them, the underwater optical wireless communication (UOWC) is characterized by high propagation speed and large transmission bandwidth. But, the optical waves in underwater environment are significantly affected by absorption and scattering effects, which limit their transmission range. In order to enhance the performance of UOWC, designing a transmission and energy efficiency routing algorithm has become a non-ignorable issue in UOWC. In this paper, a transmission distance adaptive dual-hop (TDAD) routing algorithm is proposed for underwater optical wireless networks (UOWNs) to improve their efficiency in packet-delivery and energy-consumption. Unlike the existing routing algorithms designed for UOWNs, which pre-set the transmission range of network nodes, the proposed TDAD algorithm adaptively selects the transmission range for each node according to the diversity of heterogeneous service requests and employs location and energy information in its dual-hop based routing procedure. Simulation results indicate that the proposed TDAD algorithm remarkably improves packet delivery rate with more balanced energy consumption when compared to the deviation angle-based single-hop (DAS) algorithm and the distributed sector-based (DS) routing algorithm.

水下光无线网络的距离自适应双跳路由算法

近年来，采用声波、射频和光波的三大类水下无线通信引起了人们的浓厚研究兴趣。其中，水下光无线通信（UOWC）具有传播速度快、传输带宽大的特点。但是，光波在水下环境中会受到吸收和散射效应的严重影响，从而限制了其传输范围。为了提高 UOWC 的性能，设计一种传输和能效路由算法已成为 UOWC 不可忽视的问题。本文针对水下光无线网络（UOWN）提出了一种传输距离自适应双跳（TDAD）路由算法，以提高其数据包传输效率和能耗。与预先设定网络节点传输距离的现有 UOWNs 路由算法不同，所提出的 TDAD 算法根据异构服务请求的多样性自适应地选择每个节点的传输距离，并在其基于双跳的路由过程中采用位置和能量信息。仿真结果表明，与基于偏差角的单跳（DAS）算法和基于分布式扇区的路由（DS）算法相比，所提出的 TDAD 算法能显著提高数据包的传输速率，且能耗更加均衡。
