| Abstract | Now days, Internet of Things (IOTs) plays an important role due to sophisticated state-of-the-art low power, low-cost wireless technologies. There are different areas that have witnessed an ever-increasing application of IOTs like smart home, smart city, smart industry, and smart factory etc. In each of these applications, an important aspect is to localize the person/ object/ device with an acceptable precision and accuracy. All the devices are interconnected to each other via internet in IOT. Localization can be categorized as measurements based on distance, angle, area etc. There are a slew of wirelesses technologies like WiFi, bluetooth low energy (BLE), radio frequency identification (RFID), ultra-wideband (UWB) etc used for achieving reliable localization in IOT based system. UWB has been found to play an important role in localization in IOTs due to a high frequency range (3.1GHz10.6GHz), low duty cycle (maximum on time 5ms and off time 38ms),high accuracy of ranging(cm),usage of very small pulses(ns to localize), ability to penetrate through the obstacles, capability to avoid multipath fading etc. In a wireless sensor network (WSN), it gives robust performance and has been investigated to be a potential candidate for indoor localization. This paper represents the low energy UWB pulse for localization in an IOT based system and the use of channel impulse response (CIR) of a UWB channel model 4(CM 4) in carrying out localization. © 2021 IEEE. |
