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...
The IEEE 802.15.4 standard protocol for Wireless Sensor Networks (WSNs) offers several advantages, such as the low power consumption, which can also be applied in industrial environments. However, many researchers highlighted some limitations also. For example, the CSMA/CA algorithm, that manages the access to the medium, is a contention-based approach and, as a consequence, it is non deterministic...
