Abstract

This article deals with implementation of a time distribution protocol among limited resources wireless sensor devices. This type of protocol aims to distribute the same time reference among two or more devices within a network. Timestamps on measures help to relate them on causality studies. The PTP protocol defined at IEEE 1588-2008 is used, with little adaptations, to synchronize and tune software clocks inside the target boards of the Texas Instruments  ez430-RF2480ZigBee kit. Initially only synchronization was done, but it was verified the need to implement clock tuning. The devices clocks can be synchronized and tuned, even in heavily limited resources devices.
