The technological developments are focused on automation of control systems. Technology is used in homes to create a digital environment such as controlling room temperature, sundry devices, security and lighting. The design of home automation systems is geared towards the automation of processes like remote control of the home environment appliances. The use of Wireless Sensor and Actuators Networks (WSANs) in home automation is a growing trend. WSANs are based on network architecture and protocols in order to enable a network of integrated devices which monitor and control household apparatus.
