The use of wireless technology in home and industrial automation systems is on the rise due to several advantages such as cost reduction, easy placement and installation, easy extension, comfort benefits, and mobile device connectivity. This paper provides a comparative study of different wireless protocols such as ZigBee (over IEEE 802.15.4) and Bluetooth (over IEEE 802.15.1) for the selection of appropriate technology for Load Control. It also describes a project model for remote controlling and monitoring of various loads/appliances and a means of efficient power utilization through real-time power level indicator with the help of a PC-based GUI application. Further the analysis of various performance parameters such as Latency, Received Signal Strength Indicator (RSSI) value, Round-Trip Delay time (RTD), Network coexistence of the ZigBee technology are evaluated for the implemented system.
