In this paper, the authors propose a cascaded Zigbee approach to monitor more than one room/block/floor from a remote distance and achieve control over switching without line of sight at a very low power. They have implemented Zigbee in master-slave configuration successfully; for two locations (slave Zigbee) at maximum distance of 30 meters apart from a control room where master Zigbee is placed. This paper introduces the conceptual understanding and strategy of Zigbee IEEE 802.15.4 standard to be deployed in smart home/industry/campus environment. Zigbee technology offers a multi-hop communication capability for low rate data transfer.
