ABSTRACT
The advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when a wired connection between a remote appliance device and the control unit might not be feasible. The system is wireless and uses the user’s mobile handset for control and therefore the system is more adaptable and cost effective. The system uses GSM technology thus providing ubiquitous access to the system for appliance control. With this hypothesis, three different approaches have been proposed and implemented in this project; FIRSTLY, home control switch/household appliances are controlled by server mobile which acts as remote control. SECONDLY, GSM-SMS messaging technology is used to control them from remote places and FINALLY, to provide a multiple agents environment.
