In this paper the use of dynamic reconfigurability is being explored. Here the commercially available reconfigurable device Field Programmable Gate Array (FPGA) is used for dynamic reconfiguration. The target device used here is Virtex-4 FPFA. The use of FPGA in Wireless Sensor Networks may reduce some of the major constrains of wireless sensor network such as larger bandwidth, input/ output constrains, flexibility and time-to market. This project gives the best use of reconfigurable device like FPGA in wireless sensor networks. In this paper a single wireless sensor node with one analog sensor one digital sensor and an actuator is taken into consideration and it is simulated using FPGA device and results are determined. This paper gives an idea of advantages of FPGA over microcontrollers in wireless sensor networks.

Wireless Sensor Network (WSN) is an immense area of exploration and it plays a vital role in today's electronicindustry. An application of wireless sensor network will have hundreds or thousands of wireless sensor nodes present in its environment. This makes deployment and support of a WSN a complex task. In this paper the utilization of runtime reconfigurability in wireless sensor network is being explored. Here the commercially available reconfigurable device Field Programmable Gate Array (FPGA) is used for runtime reconfiguration. The target device used here is Virtex-4 FPGA. Here a single wireless sensor node with two analog sensor, two digital sensors and two actuators is taken for the development of a wireless sensor node and it is programmed in a wireless sensor network with the help of a remote system. In the system the single node is divided into two modules one fixed and the other reconfigurable. The reconfigurable module is partially reconfigured into the system while the fixed part is in function in the end node.
