Comparative Analysis of Di erent Methods for Reducing the Energy Consumption and latency in NB-IoT systems

Abstract

The internet of things or IoT is a new and rising technology. Which compromises of a new kind of UE with di erent kinds of needs. This opens up an entirely new eld of communication technology, Low Power Wide Area Network or LPWAN for short. To compete with rising LPWANs like LoRa and Sigfox, 3gpp, on release 13, froze the speci cations for NB-IoT. Inheriting many features from LTE, NB- IoT was developed with ample opportunites for improvement. In this paper, we compare the various methods that were used in NB-IoT to reduce energy consumption and latency with novel methods re- searchers have proposed in recent years. To ultimately come up with an optimized NB-IoT with the most conservative amounts of energy consumption and latency.
