An Ultra-low Power Consumption MAC Protocol Complied with IEEE 802.15.4/4e for Wireless Smart Utility Networks

Abstract

In gas and water utilities, the spread of ultra-low power Wireless-Smart Utility Networks (Wi-SUN) has been predicted. This paper proposes a novel MAC protocol (F-RIT protocol) complied with the RIT in IEEE 802.15.4e standards to implement the wireless SUN in the gas and water utilities effectively. The proposed protocol is compared with CSL in IEEE 802.15.4e in terms of power consumption and success rate of communication link establishment. Theoretical and simulated evaluation results show the effectiveness of the proposed protocol under conditions of high terminal density and highly communication link request. In addition, a potential of F-RIT protocol regarding improvement of performance and expansion of application is described. MACIEEE 802.15.4e U-Bus Air

Efficient Polling Communications for Multi-Hop Networks Based on Receiver-Initiated MAC Protocol

“…Figure 5 shows the collection success rate characteristics for polling intervals when the maximum number of additional addresses χ is set to 0, 3, 6, and 9. The collection success rates in all parameters achieve over 99.5%, which is a target rate of wireless systems for critical infrastructures [3], since the channel fluctuation is not considered in this paper. The proposed enhanced source routing scheme may increase the frame length of the DATA, but the collection success rate does not decrease because collisions are avoided by polling communications.…”

“…In the Wi-SUN JUTA profile, the interoperability of the F-RIT protocol [3] is assured based on IEEE 802. 15.4-2015 [1] in the physical (PHY) layer and the lower part of the MAC (Low-MAC) layer [26].…”

“…If there are multiple potential receivers to transfer the data, the expected waiting time for the RIT data request frame from the receivers decreases. The feature of the receiver-initiated MAC protocol is that the waiting time at the Tx wait duration is dominant for the delay and the current consumption [3]. Therefore, the improvement of the delay and the current consumption is expected by setting multiple candidates to transfer data in downlink communications.…”

“…In the F-RIT protocol, the transmission interval of RIT data request frames (i.e., the MAC RIT period) is the dominant parameter for the current consumption of terminals [3]. The shorter interval can reduce the delay and the power consumption to transfer a DATA, because the listening state of the Tx wait duration to wait for the RIT data request from the destination terminals is shorten.…”

“…The key technology to achieve the low-power operation for the battery-powered devices is the low-power media access control (MAC) protocol. Mainly for gas and water meters, the feathery receiver-initiated transmission (F-RIT) protocol has been proposed [3]. The F-RIT protocol was developed based on the RIT protocol standardized in the IEEE 802.…”
