В работе обсуждаются вопросы синхронизации часов узлов сенсорной сети, рассматриваются существующие подходы. Работа также описывает опробованный на практике механизм, позволяющий сократить расходы электроэнергии на работу устройства, не потеряв при этом в точности определения времени. Предлагаются методы коррекции расхождения часов устройств и учёта температурных поправок.

Time synchronization in sensor networks
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.
