Various sensor networks use different data storage and management mechanisms. In particular, UCLA’s ESS2 mechanism forwards information from low powered 8-bit Mica2 motes to one or more low powered sinks that then push log files to a secure and centralized repository. While this data storage and management mechanism is straightforward to implement, publishing and sharing various data to various users has been a challenge. Users that need to parse the data often find it time consuming and error prone to have to log-on to different systems, calibrate different units, and to understand the different semantics of various log files.

Similar to blog sites, SensorBase.org is our solution for a certain domain of sensor networks that allows users to “slog” sensor network data and other relevant information. It is a centralized common data storage and management system that provides a uniform and consistent method for publishing and sharing data. It allows users to define a subset of EML data types, project groups, and permission levels. It also serves as a search engine that provides APIs a way to easily query for specific data sets based on geographic location, sensor type, date/time range, and other relevant fields.
