It connects field devices for discrete applications while HART and WirelessHART
connect field devices within process applications.

In conformity with these rules, there are a few research works over WirelessHART
The move is part of Pepperl+Fuchs' strategy to further extend its integrated solutions offerings and strengthen its position in the WirelessHart
Emerson Process Management's Smart Wireless Gateway 1552WU is a Wi-Fi access point that connects WirelessHART
sensors to the control network.
Wireless connectivity can be implemented using either IP oriented protocol stacks like 6LoWPAN, WiFi, or using non-IP standard protocol stacks such as Zigbee, XBee, WirelessHART
, wM-Bus, Bluetooth or proprietary stacks like SimplicityTI .
These intelligent P2P wireless networks use frequency-hopping spread-spectrum radio networks and WirelessHART
networks to self-organize communications paths through other nodes, auto detect new devices and self-heal communications paths based on node failure or path bandwidth overload.
This edition has been updated to incorporate events since the last edition and an analysis of new wireless technology for process control, such as ISA100 Wireless (ISA100.11a), WirelessHART
, WIA-PA, and wifi, including IEEE 802.11n and 802.11ac.
The most widely applied standard in WSN is the WirelessHART
(highway addressable remote transducer) [3, 4] which is a variant of HART with a simple, reliable, and secure communication between wireless devices for an industrial automated process.
Therefore, there are increasing research and standardization efforts, such as time-synchronized mesh protocol (TSMP) , IEEE 802.15.4e, ISA100.11a, WirelessHART
, and other related protocols, into developing multi-channel communications protocols.
