Implementation of Network-centered Software Platform for Wireless Sensor Networks

Abstract

Wireless sensor networks are data-centric, in which data management and representation is a crucial issue. In this paper, sensor networks deployed to monitor wetland and underwater environment by multi-hop networks are equipped with the Network-centered Software Platform to visualize the data and topology. Our visualization software platform adopts three- layer model as architecture. The three-layer model equips our visualization software platform with favorable flexibility, scalability, better security, higher reusability and good fault tolerance. The technologies involved in this paper include serial communication, database management and data visualization which is to visualize the data gathered by wireless sensor networks. The database can be accessed by both local users and remote users through Internet. Of course the users must have an authority to know the conditions of wireless sensor networks. Practical experiments have illustrated that our visualization software platform can get data from the wireless sensor networks and provide real time and historical information for users. It is convenient and efficient.
