From the report, we see that the SMS is sent from the controller's mobile to the mobile phone connected to the home appliances. The details you should know when going ahead with the project are:
-about AT commands which are included in the GSM specification. Almost all phones support this AT commands. The commands to control the device are transmitted to the end mobile phone as AT commands.
The AT (Attention) commands set used in communication is covered in the report and more you can learn from the net.
-Microcontroller programming
The message recieved by the end mobile phone is taken by the microcontroller and decoded to fetch the AT command sent by the user. Then the microcontroller will switch the devices on and off by controlling the relays. The programming is simple and if you have basics of C/C++ programming, you can write the code easily. The requirements of the program are available in the document.
