Wireless Sensor Networks (WSNs) consist of a number of nodes and if new application code (application update) should be downloaded to all nodes or some group of nodes then this application code have to downloaded to each node individually for example via USB interface or via programmer. This operation consumes much time and it is pretty annoying. The idea of this project is to deploying the application code via radio transmission from one central node/computer to appropriate group of nodes in network. Each node in network runs daemon monitor software which on background receiving application code via radio interface and starting this code up. Such Monitor software will be an objective of this project.
