Abstract: 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.

Key words: Wireless sensor network, Ocean scene, Network architecture
