A Novel FPGA-Based Multi-Channel Multi-Interface Wireless Node: Implementation and Preliminary Test

The implementation and the preliminary test of a novel FPGA-based Multi-Channel Multi-Interface (MCMI) wireless node is presented in this paper. The MCMI wireless node was developed using a Xilinx Spartan-3E XC3S500E FPGA development board. The CC2500 RF transceivers as low-cost low-power wireless radio modules operating in 2.4 GHz ISM band were connected with the FPGA board via a Serial Peripheral Interface (SPI). The implementation result shows that the designed FPGA-based MCMI wireless node architecture uses small amount of resources of the Xilinx Spartan-3E XC3S500E FPGA. Consequently, we can further include more algorithms or functions on the top of our proposed system. The experimental result from a preliminary test scenario also demonstrates that the FPGA-based MCMI wireless node improves the packet delivery ratio to reach 100 % while varying traffic loads.
