A Review on Application Specific Wireless Sensor Nodes using FPGA
Keywords:
Spartan III FPGA development board, Xilinx 12.2, Modelsim 6.3c, JTAG cable, and power cable.Abstract
Nowadays in embedded systems technology, energy efficient sensor nodes are the most growing
application. Basically wireless sensor nodes contain the Sensing unit, Data acquisition unit, Transceiver unit,
Power unit. In data acquisition unit processing part contains mostly programmable micro-controller and
digital signal processing, but this result in higher power consumption than actually needed by application
specific sensor node. The current research work shows that flash FPGA technology can be implemented for
precisely application processing for sensor nodes with efficiency of energy and upgradability towards its
application. That rivals to the general purpose processor solutions. This will save the materials of hardware
and also a workload of software. As the same hardware chip is use for the processing unit and transceiver unit.
So this result gave the way for the new type of self-powered sensor nodes, which can be configured according
to their specific application.
