A reliable hardware platform for wireless sensor networks

A wireless sensor network (WSN) is a spatially distributed autonomous sensors to monitor physical parameters. The major study in this paper is to design and implement a highly reliable hardware platform at ISM radio bands (i.e. 2.4 GHz) to be employed in a WSN system. ISM radio bands are reserved internationally for industrial, scientific and medical purposes. ZigBee-IEEE 802.15.4 is one of the most emerging technology for WSN. ZigBee Vendors supplying Coordinator, Router and End node separately. In this paper we present a device, can be configurable as Coordinator or router or End node. This device consist MSP430F5438 as microcontroller and CC2520 as RF Controller. Microcontroller part consists of JTAG, USB, Analog Inputs, Digital IOs (i.e. UART, SPI & I2C) and for better performance added Inverted F-Antenna, Matching Circuits and Balun Circuits to CC2520. Schematic translate to Printed Circuit Board by EDA tool Cadence-OrCAD. From our device, transmitted distance up to 25 meters without data loss.
