Energy Consumption Performance on IEEE 802.11ah Networks with Station Grouping Scheme

Abstract

Sending packages from the sender to the recipient at the station requires adequate resources. To ensure messages in the form of text, data, images, and videos are received in real-time, reliably, and flexibly, power performance with low energy consumption is required at the station. IEEE 802.11ah can be one of the wireless technologies to overcome this problem by saving low power consumption, the transmission range of 1 km and access points can reach 8191 stations. The purpose of this study was to determine the performance of energy-saving consumption by station grouping which is regulated in the regulation of the number of RAW slots. From the results of this study, energy savings were obtained by dividing the two groups when the station numbered 900 stations with an energy consumption of 8.105 joules while in one group with a smaller station scale the total energy consumption of 8.124 joules was obtained. The second scheme is by dividing slots (NRawSlot) to reduce energy consumption in large station capacities. The NRawSlot division is divided into seven-slot with energy consumption of 8,105 joules. It is proven that energy consumption is more efficient by grouping with more station capacity.
