Abstract
A system and method are provided for distributed data collection synchronization. Provided are communicating data generation units (DGUs) capable of data storage, having consumable power resources. In response to the DGUs comparing their availability and power resources, a master and slave DGUs are selected, and the slave DGUs synchronize their data collection to a common timing reference supplied by their master DGU. One example of consumable power is battery power. A first DGU may select itself as a master DGU in response to either waiting a first predetermined duration of time after reset, or receiving no link status message from a master DGU for a second predetermined duration of time. Alternatively, a slave first DGU may compare its own available power resources to the available power resources of its master second DGU and select itself as the master DGU when the available power resources of the first DGU are greater.
