Architecture of wireless sensor network for monitoring aquatic environment of marine shellfish

Abstract

Aquatic environment monitoring plays an important role in the artificial breeding of marine shellfish. Wireless sensor network (WSN) is an efficient approach for monitoring large-scale coastal beach with densely distributed smart nodes. Combined with a project of aquatic environment monitoring and assessment of marine shellfish in Zhejiang province, China, a new structure of WSN combining network clustering and route enhancing is proposed with the aim at facilitating node deployment in offshore and tidal zone and regular network maintenance. The topology of wireless sensing cluster, hard- and soft- design of wireless node and routing enhancement are elaborated. The testing result shows that the proposed scheme has the capability of robust data transmission. The method proposed in the paper is also suitable for other water quality monitoring system.
