Design and Implementation of Middleware in Sensor Networks Using Publish/Subscribe Model

Wireless sensor networks are attractive means to monitor environment and to utilize for military. Sensor networks are increasingly improving. Operating system and routing are especially researched in times past. On the other hand, the aspect of middleware that sits between the operating system and the application did not be sufficiently discussed. The importance in sensor networks is power saving. And middleware is located between operation system and application. Middleware in sensor networks is responsible to process data effectively to minimize spending energy of sensors. Therefore this paper proposes to effectively process data using data fusion technique.
