The use of field programmable gate array (FPGA) can improve the processing performance of many systems,\r\nincluding wireless sensor networks (WSNs). Moreover, FPGA devices permit remote and runtime hardware reconfiguration,\r\nwhich implies benefits in WSNs deployment and maintainability and finally, cost reduction. Thus larger circuits can be realized\r\nusing this module. Along with the logical implementation the wireless sensor node has also been designed and implemented to\r\nexhibit the functionality of the node�s transmitter, receiver and main controller before the actual deployment. Therefore, the\r\nnode will support only those hardware components required by the target application and that will reduce the node power\r\nconsumption. In this work the main task of FPGA based emulator is to optimize power requirement and analyze performance of\r\nreal time applications in WSNs.
