Data Correlation in Sensor Networks

Constantin-Daniel Oancea

Abstract

Sensor networks provide a number of benefits by being a group of independent elements that communicate with a central node. Since it has possible that correlate data sensor, the issue of data timestamp become. The paper presents a revise of methods to give timestamp of data from sensor network. Each sensor can provide along its own data, time information, useful when aggregate them. The proposed aim is to compare various technologies, like GPS and DCF77 with their own limits and benefits.
