Abstract
The wireless sensor networks (WSN) have for a time now been receiving an sizable
amount of interest of the academic community. This can be attributed to the rapid
advancement of the microchip and sensor technologies, which made possible a vide
new array of real-world applications. The WSN are opening the road for applications
that will help farmers increase the quality of their produce, that will help with
mitigating the impact of human activities on global warming, and that will make
the research in other scientific areas easier, amongst other things. However, the
practical problems related to the deployment of the WSNs - synchronization problem
included - are far from solved for good. This thesis aims to investigate the issue
of synchronization in WSNs and the issue of clock skews. Next, some of the most
widely discussed synchronization algorithms, as well as the implementation of one
of them will be presented. Finally, the results of the experiments conducted will be
presented, confirming the established knowledge regarding the relative clock drifts.
