The Design And Implementation Of A Flex-based Middleware Management System Of Sensor Network

The sensor network is all distributed networks which contains large of tiny nodes that consist of sensor, the model of data consulting and Communications model. The management system of sensor network provides integration of Management mechanism to the resource allocation, performance, failure and security of system.We could efficiently monitoring control the sensor network, have large influence on improving the performance of sensor networks. The management system of sensor network adopts the background middleware management which is based on OSGI framework, supports the functional modules which can be loaded into the middleware as bundle. It’s convenient for software to updating, upgrading and the functional expanding. Otherwise, Flex is a leading programming language for client of Rich Internet Applications,which can be used to construct the fashion-show Web application. These applications use Adobe Flash Player and Adobe AIR. The cross-browser, desktop and OS are running consistently. So, constructing a new middleware management system to control and manage the system of sensor network has the relevant meaning. It could consult all kind of data, and is good at the accessing of any business.This paper summaries and analysis the sensor network and management of sensor network, then introduce the functional needs, performance needs and the running environment needs. At the basic of needs, I designed the whole framework of middleware management system, made the front client which is based in Flex and the background server that is based in OSGI. The background server makes all functional modules of middleware into independent Bundle, which contains data processing, communications between front client and background server and so on. It has the ability of receiving the SQL orders, user’s orders and the background’s data. The front management system uses the pure MVC to construct the whole framework, which has the search functional, user functional, topology functional and the user identity functional. It also designs the programming agent to communicate with background server. At last, I construct the testing environment to use the sensor nodes and receiving interface to get data, and test all functional of the management system. The result of test shows that the management system of sensor network could meet the needs of the management.
