Compression Offloading in Wireless Sensor Networks
The goal of compressing data in sensor networks is to minimize the amount of data stored on internal flash as well as transmitted over the network. Compressing the data will minimize packets constructed as well as overall memory usage. The novelty of this project is that it is hardware assisted. The hardware to be used is the MICAz mote by CrossBow. The FPGA used is the Cyclone II by Altera.
The main difficulty for such a system is interfacing the FPGA and the MICAz. The compression module on the FPGA will have to be optimized for low power. Additionally, there will have to be a module which does I2C communication (unless another means of communication is chosen). The MICAz will upload bulk data and receive the compressed format. The mote can then either store it in its internal flash or transmit it over the network.
The compression module will be written in Verilog and designed in Quartus II. I will look for provided modules for power aware compression.
