Node Synchronization Across Two-layered Heterogeneous Clustered Wireless Sensor Network

Gundars Miezitis, Romans Taranovs, Valerijs Zagurskis

Abstract


Time synchronization is a mandatory feature needed for Wireless Sensor Network to operate consistently and to be capable to chronologically link to global time. Time synchronization is important when the sensor nodes employ TDMA [9] based medium access protocols and when sensor nodes want to operate on some time managed schedule as well. Time stamping is one of the most widely used approaches, because of simple implementation and of being quite precise. Based on the time stamp exchange approach we provide network wide synchronization that employs neighbouring node information to determine if synchronization should be continued on the same level or in the second level of nodes.

Keywords:
Synchronization, two layered network, wireless sensor network.
