Ultra-low power MAC protocol complied with RIT in IEEE 802.15.4e for wireless smart utility networks

This paper proposes a novel ultra-low-power media access control (MAC) protocol, called the feathery-receiver initiated transmission protocol (F-RIT), complied with RIT in the IEEE 802.15.4e standard (15.4e). The proposed F-RIT protocol uses compacted 15.4e MAC frames to reduce power consumption. Additionally, a simplified channel sampling process, called pre-carrier sense (Pre-CS), is introduced to the proposed F-RIT instead of carrier sense multiple access with collision avoidance (CSMA/CA) in 15.4e RIT to improve time utilization efficiency per a channel. The proposed F-RIT can improve the success rate by more than 5-fold relative to the coordinated sampled listening (CSL) protocol, another low-power-consumption protocol of 15.4e, in an environment containing 100 terminals, where each terminal transmits its signal for 100 ms, and the data transmission data occurring 0.01 s

per a terminal.
