Mobile applications using TCP/IP-GSM protocols applied to domotic

Now, the devices that can to be connected to internet are increasing, this has allowed to develop new technological innovations in automation and domotic fields. This paper presents an application of Internet of Things (IoT) applied to domotic, in which a domotic network for control and monitoring has been designed and implemented. In the implementation process different electronic modules low cost are used, the most important module is Arduino, connected with others mobile devices which have different communications interfaces. In this context, the TCP/IP protocol be used for data transmission over internet, thanks to easy access to internet on mobile devices, also it has implemented an android app using diferent plataforms as Android Studio and App Inventor. In android app implementation the manual and voice commands for controlling and monitoring all devices into domotic network since a smartphone has been included, at the same time a security network using a Global System Mobile (GSM) network through of Short Message Service (SMS) using the RS 232 protocol was developed and implemented, this process are doing when the user do not have a stable internet connection in the smartphone and needs to have control of impotant devices into domotic metwork.
