Analysis of Data Rate and Transmission Power Hybrid Control in WSN IoT

Abstract

The relationship between data rate and transmission power is analyzed in this paper. Moreover, an algorithm
combined with adaptive data rate (ADR) and transmission power control (TPC) is proposed
in this paper, and it improves battery life significantly on IoT devices. In the premise that without
prejudicing the accuracy of wireless transmission, the faster data rate and lower transmission power
can be used to reduce power consumption. The results of a longtime test show that the nodes with
the proposed algorithm not only achieve power saving when good transmitting environment, but also
accomplish stable communication in the harsh environment. In the best case, compared with the noalgorithm
nodes, the nodes with the ADR and TPC algorithms can be reduced power consumption
up to 50%.
