OVERVIEW OF TIME SYNCHRONISATION TECHNOLOGIES FOR WSN
摘要
Abstract
Time synchronisation is the basis of the technologies of data transmission,node localisation and network scheduling in wireless sensor network (WSN).Limited by low power consumption,low complexity and low bandwidth,the time synchronisation technology in traditional network cannot meet the requirements of WSN.Based on introducing current research status of time synchronisation technology in WSN at home and abroad,in this paper we present typical clock model of node,conclude classic time synchronisation mechanism,summarise a variety of novel time synchronisation protocols such as firefly synchronisation,mixed time synchronisation,distributed time synchronisation, etc.,and point out the shortages existed in current time synchronisation technologies for WSN.Finally,we present the prospect of the development trend of time synchronisation technologies.关键词
