Mathematical Modeling for Time Synchronization in WirelessHART Networks: Survey and Research Challenges

WirelessHART network is a kind of emerging wireless sensor network (WSN). Based on the current research of time synchronization in WSN, this paper summarizes and improves the mathematical modeling schemes of time synchronization, and makes a detailed analysis for their application in wirelessHART. In addition, this paper also puts forward some new time synchronization models for further research. Finally, the potential challenges and the possible research hot spots for time synchronization of wirelessHART are roughly forecasted in his paper.
