A Web Services Based Email Extension for Remote Monitoring of Embedded Systems

Nowadays, remote control applications via the Internet are going to be used more and more widely with the development of powerful chips and network technology. For applications which do not need real time communication or persistent connection and have a little amount of data transportation, conventional approaches based on Web services either are a little bit complex, or have a higher overhead. In this paper we introduce another method called WeeRMES, a Web services based email extension for remote monitoring of embedded systems, to be supplement of conventional remote control methods in some special occasions. Thanks to the model, we are able to do all those things using emails such as sending devices instructions, inspecting device status and gathering data using XML capsulated messages. User interfaces can be dynamically achieved by means of XForms generated by Java classes loaded on target devices. Furthermore, researches are carried out on security mechanism to ensure safety and robustness of the system. An idiographic implementation is given as an example in the end.
