SCADA systems development on mobile device platform - Java']Java client/server model and localization enhancement

The paper deals with the subject of programming possibilities SCADA systems in the context of mobile devices as well as in relationships with control systems and problems with solutions of possible situations arise from their design or their operation. The main objective is to provide complex view on branch of knowledge and to show possibilities how to use SCADA systems on concrete mobile device in context of use Java language. Main aspect is in Java language and use of created SCADA based application on wide scale of mobile devices without any changes of source code. The proliferation of mobile computing devices and local-area wireless networks has fostered a growing interest in location-aware systems and services. Another area of interest is in model of radio-frequency (RF) based system enhancement for locating and tracking users of our SCADA system inside buildings.
