Data Collection and Transmission

Solved technical problems:
Data Sensing- Interfacing sensors on the motes (Direct Data, e.g. temperature, light intensity etc)
NesC provided ADC Module to communicate with the sensors. It allow us to grab the sensor’s reading via the ADC(Analog Digital Converter) interface.

Data Transmission – Broadcast (will implement more advance routing algorithm if has extra time)
Broadcast is the simples data transmission method. A sensor mote will simply forward the message around the network until the base station receives it.

Data logging - Interfacing MySQL Database
I have successfully collected the data from the wireless sensor network and log them into database.
Figure below showed that the counter data have been logged into the database.


Technical problems to be solved:
Request injection -(On-demand data request or mode changing (e.g. periodical -> realtime))
Allow user to change the data sensing behavior.

High frequency sensing - (Indirect Data)
Collecting data that require high frequency sensing and processing.
