Program Systems Institute of RAS, Pereslavl'-Zalesskii, Yaroslavskaya obl.

Abstract: The paper analyzes the problems of time synchronization in sensor networks, reviewing current approaches. The paper also describes how two crystall oscillators can be used to provide both high precision time mechanism and relatively low energy consumption. Moreover, the paper presents method for sensor nodes' clock skew correction.

Key words and phrases: sensor networks, time synchronization.
