研究了传统无线传感器网络体系结构的缺陷,分析了海洋场景的特点,总结了基于海洋场景的无线传感器网络的典型需求目标,归纳出海洋环境中无线传感器网络体系结构模型设计的若干原则。结合海洋环境自适应、网络自愈合、能量高效、动态优化等目标需求,提出了一种面向海洋场景的无线传感器网络体系结构模型WSNAOS,并对WSNAOS模型的设计理念、主要特色、各层和各模块功能进行了详细阐述。WSNAOS模型不仅具备了海洋环境自适应和能量高效等特征,还能为面向海洋场景的无线传感器网络各类协议的研究提供一个统一的问题描述和分析的理论框架。
The defects in traditional wireless sensor network(WSN)architectures were firstly studied,then the characteristics of ocean scene were analyzed.The typical requirement objectives of WSN based on ocean scene were acquired,at last a set of design principles for WSN model in ocean environment were concluded.According with the objects ocean environment adaptive,network self-cure,energy efficient and dynamic optimization,a wireless sensor network architecture model for ocean scene(WSNAOS)was proposed.Furthermore,the design thinking,general characteristics and functions of every lay or every module were described and discussed.WSNAOS not only has the characteristics:ocean environment adaptive,energy efficient and so on,but also supplies the research of WSN protocols in ocean scene with a common problem description and an academic framework.
