This report gives a problem description and an overview of the area of sensor control and management of sensors connected to a communication network in a network centric warfare situation. We describe important areas like the sensors themselves, the constraints, the character of the control goals, control decisions and the problem structure. We have also described in more detail other topics like analysing the information need, defining management policies, resolving conflicts, distributed sensor control, planning as well as autonomous control. We also note the problem of how to assess systems containing sensor control functionality and describes some application areas. The sensor control problem is a very complex problem that lacks a unifying theory or model. A first attempt to some parts of a unifying theory is described/proposed in this report
