Analysis of RSSI in diverse field

IEEE.802.15.4 based ZigBee will play an vital role in the future of different fields of wireless communication due to its long battery life and less power consumption. The RSSI of radio signals used to estimate the distance between ZigBee nodes and it does not require any hardware additionally other than simply a radio transceiver. In my study, I analyze the importance of RSSI(Received signal strength indicator) under diverse application of ZigBee such as medical, mobile robot application, Industrial, indoor localization and Agriculture field.
