Compression method for resource constrained local area networks

A compression method for resource constrained local area networks comprising the steps of:

• establishing one or more sensor nodes within a wireless local area network, a sensor in each sensor node monitoring a physical condition and generating an electrical signal representing the physical condition, the wireless local area network including a base station, said base station receiving data from each sensor node and communicating with a server,
• acquiring by each sensor node baseline data sets,
• transmitting via the wireless local area network to the base station the acquired baseline data sets,
• storing the received baseline data sets as references by the base station,
• acquiring by each sensor node subsequent data sets at periodic time intervals,
• performing by each sensor node mathematical operations on the baseline and subsequent data sets to determine similarities between baseline and subsequent data sets,
• determining by each sensor node a difference between baseline and subsequent data sets to generate difference data sets,
• compressing the difference data sets by each sensor node using a combination of precision reduction and truncation,
• transmitting by each sensor node the compressed difference data sets via the wireless local area network to the base station, and
• reconstructing at the base station original data sets using the stored baseline data sets and the received compressed difference data sets.
