摘要
水声网络具有高延时、低带宽、能量有限、高节点移动性的独有特性,这使得水声网络中MAC协议的设计面临巨大的挑战。本文对水声网络中MAC协议进行综述性研究与分析,介绍水声网络的现状;分析水声网络中MAC协议设计主要面临的四种挑战;对于现有的水声网络中MAC协议进行分类分析,分析每类的水声网络MAC协议的优缺点;对未来水声网络中MAC协议设计进行展望。
Underwater acoustic networks have the unique characteristics of high delay,low bandwidth,limited energy and high node mobility,which makes the design of MAC protocol in Underwater acoustic networks face a huge challenge.In this paper,the MAC protocol in Underwater acoustic networks is reviewed and analyzed,and the current situation of Underwater acoustic networks is introduced.Four main challenges of MAC protocol design in Underwater acoustic networks are analyzed.The MAC protocols in the existing Underwater acoustic networks are classified and analyzed,and the advantages and disadvantages of each type of underwater MAC protocol are analyzed.The future design of MAC protocol in Underwater acoustic networks is prospected.
