Simulation of dynamically reconfigurable wireless sensor node

Abstract

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.

Run-Time Re-configuration using FPGA for Bio-Medical Application

“…Runtime partial reconfiguration is medical application. Major reasons to shift to FPGA include the following aspects: improve execution time, increase in privacy, elimination of positive embedded constraintsrestrained power consumed, and precise event disturbance protection [7]. Along with these there is increase in control performance; execution time is decreased dynamically reconfiguring it.…”

ANFIS Analysis of Wireless Sensor Data with FPGA

“…They improved the efficiency of sensor systems by their architectural flexibility, re-configurability, processing capabilities, interfaces. They also perform many simple and complex functions [14] [15]. These types of sensors are usually used for high-speed applications that need online measurements.…”
