A time synchronization scheme for wireless HART
Pang Ta · Automation and Instrumentation · 2010
WirelessHART protocol and communication network is design for HART fieldbus in process control,the network-wide time synchronization is necessary for the secure,reliable,error-free communication between HART devices in wireless-hart network.The paper present a time synchronization scheme which is applicable for wireless-hart network based on the analysis of the wireless-hart protocol,IEEE 802.15.4 protocol and each existing time synchronization techniques(NTP,TPSNN,RBS).
