Research And Implementation Of Data Acquisition Software And Networking Algorithm For Wireless Sensor Node Telosb

Ocean is the huge resources of treasury and human's wealth of sustainable development. The development and exploitation of ocean is the research emphasis. The rich resources are existence in waters, which accounted for 70% of the earth. In recent years, with the rapid development of the technique of wireless sensor technology, network communication technology and embedded systems, wireless sensor networks is effective used for marine environmental monitoring by using flexibility, real-time monitoring and self-organization of wireless sensor network deployment.Based on the monitoring system of offshore wireless sensor network and the research platform for the networking of underwater sensor networks, the data acquisition software and networking algorithm for wireless sensor node TelosB is presented. The monitoring system of offshore wireless sensor network is a real-time monitoring system for offshore, which is constructed by lots of wireless sensor nodes. This system is an automatic monitoring system without manual involvement and experimental platform for validating laboratory achievements, which runs automatically by the program from data collection to the data import to the database. Data acquisition software plays an important role in this system. The networking of underwater sensor networks is developed by the deployment of underwater sensor nodes. According to characteristics of underwater, some researchers are forced on the network nodes and protocols. Wireless sensor nodes TelosB is used to the practical application of this platform.Research and implementation of data acquisition software and networking algorithm for wireless sensor node TelosB is introduced. First, research background and analysis for design objective is detailed described. Data acquisition software based on offshore monitor system is presented. Then, according to the different functions, the overall process flow diagram is found and wireless sensor nodes is divided into data acquisition node and sink node in monitor system. Finally, according to analysis of program's characters in TinyOS, data acquisition software program is divided into different components and developed.Wireless sensor nodes TelosB are used to the networking platform of underwater sensor networks. By analyzing TelosB nodes from hardware and software, networking algorithm and feasibility of component is addressed.
