Implementation of Wireless Sensor Network Using Microblaze and Picoblaze Processors

A wireless sensor network has a substitute for traditional wired monitoring systems. Wireless monitoring systems helps to reduce the complex wiring and power consumption of the system in tern installation cost of the system. It increases the reliability of the system for long term applications such as structural health monitoring, Health care, control and security etc. Wireless sensor network (WSN) consist spatially distributed sensors, computing and communicating elements. This system is implemented using Field Programmable Gate Array (FPGA). It has master-slave architecture. Master is designed with Pico blaze and slave with Micro blaze soft core processor. These two soft core processors are optimized for Xilinx FPGA and implemented using ISE and EDK software suite. To implement WSN on FPGA is the challenging task of the system. This will overcome precincts of traditional processor such as reliability, flexibility and very important aspect durability with high processing speed. It reduced the processing time to nanoseconds. Wireless sensor nodes are communicating using ZigBee (IEEE 802.15.4 standard). It is RF transceiver operate in 2.4-2.843 GHz ISM (industrial, scientific, and medical) band.
