Classification and Analysis of Time Synchronization Protocols for Wireless Sensor Networks in Terms of Power Consumption

摘要

Various Time Synchronization protocols (TSP) for a Wireless Sensor Network (WSN) have been developed, because a time relationship plays an important role in many WSN applications, as well. For TSP in WSN, constraints of energy as well as synchronization accuracy should be considered, especially. In this paper, we classify TSPs for WSN in terms of power consumption that is affected by synchronization style. And several TSPs are analyzed according to our classification. Simulation tests have been performed in order to evaluate the power consumption of those selected protocols.
