Abstract


With the rapid development of semiconductor, communication and sensing technologies, wireless sensor network (WSN) has become the key technology in the new era of sensing technologies. WSN nodes, which consist of sensing, data processing and wireless communication components, are deployed densely and randomly in large numbers. The nodes form the WSN in a self-organization manner. Based on the diverse onboard sensors, the WSN can sense the field and communicate the information to the remote sink in an efficient and timely manner. The sensing performance and reliability have been improved significantly in WSN. So the WSN can be widely used in military sensing, security, environmental monitoring, traffic surveillance, medical treatment, building and structures monitoring, even anti-terrorism, etc.The key technologies to support WSN including wireless sensor network node hardware platform develop and the protocol design about wireless communication system between different nodes. This article based on the key technologies of WSN as research background. Through analyzing and comparing the current commonly used plan, meanwhile analysis the wireless WSN nodes major component, choose the appropriate devices, design a kind of wireless sensor network node with fiber hydrophone. This article focuses on network node hardware circuit design. Meanwhile a preliminary protocol research about the wireless sensor network communications system, focus on the physical layer and data link layer protocol research, network layer protocol on preliminary research.There are many researches about WSN and fiber hydrophone in domestic and foreign. But combing this two into one is relatively less. We try in this aspect, hope that provided reference for other development of wireless sensor network nodes with other types of sensors, and laid foundation for further research and improvement in wireless sensor network node.
