Abstract :
Recent advances in SoC technology offer the possibility to realize the function of wireless sensor network node in a single chip. In this paper a reconfigurable wireless sensor network node for quick transmission of voice data is being described. Compared with existing works, we can implement different types of components depends on the application in which the sensor is meant to use. Using Verilog, we provide a detailed description of the implementation of MAC layer controller protocol based on IEEE 802.15.4 MAC layer protocol. An improved CSMA/CA mechanism is introduced for the transmission of voice data, enhancing its timelines and reliability. Finally, we make up testing platform for MAC layer controller. From the hardware and software simulation results, the design of MAC layer controller based on FPGA is successfully verified.
