The Design And Implementation Of Node Information And Topology Display System For Wireless Sensor Network

WSN(Wireless Sensor Network) are gradually play a great role in our life.Therefore, it has great research value and theoretical value on wireless sensor network.This paper examined the existing data visualization platform of wireless sensornetwork at home and abroad, designed and implemented a node information andtopology of display system for wireless sensor network using Flex and J2EE.The paper has mainly done the following works:1,Analyses the existing wireless sensor network visualization system at home andabroad, Many of them based on the (Client/Server) C/S architecture,but the systemwhich based on the B/S architecture is less. It may because of the B/S architect itselfexist some problems such as real-time and reliability problems. But after the demandanalysis and detailed discussion, the author believe that to develop wireless sensornetwork node information and topological structure display system based on the B/Sarchitecture is very important, because the B/S architecture has the congenitaladvantage. In addition, develop the wireless sensor network application based on theB/S architecture can also provide a data interface to the further development such asmobile phone client application and a variety of other client application, which notonly reduces the costs of development mobile phone client applications, but alsoconducive to the realization of remote monitoring.2,Analysis and investigate the advantages and disadvantages main stream J2EEenterprise development framework, and select the most suitable developmentframework for Wireless sensor networks node information and topology displaysystem. 3,The paper put forward a solution to the wireless sensor network nodeinformation and topology including real-time topology display, real-time data line chart,real-time data on network information query log, network topology information logquery module in this solution. Provide technical support and exploration for WEBmonitoring platform for further research and development of wireless sensor network.4,Using the J2EE platform and the open source MVC framework, design andimplementation of wireless sensor network node information and topology displaysystem.After testing the system can work accurately and timely response of wirelesssensor networks working status and data from the node. At the same time the system isalso a good platform to research the wireless sensor network.
