A fuzzy system to reduce power consumption in Wireless Sensor Networks: A comparison between WirelessHART and IEEE 802.15.4

WirelessHART and IEEE 802.15.4 are the most suitable protocol for industrial applications. WirelessHART, in particular, overcomes some problems related to the IEEE 802.15.4 protocol such as the maximum number of Guaranteed Time Slots during which it is possible to transmit real-time information. However, the power consumption ofWirelessHART devices is still higher than IEEE 802.15.4. This article shows a fuzzy solution for power consumption management to be applied both in WirelessHART and IEE 802.15.4 networks, through the optimization of the sleep/wakeup mechanism of the protocols. Finally, the paper shows a performance evaluation of the proposed approach in terms of energy consumption of batteries.
