Final year projects Engineering/ Diploma/ BCA/ MCA Contact 9448847874 Vensoft Technologies is a Electronic Design Services (EDS) for VLSI / EMBEDDED and MATLAB, delivering a wide variety of end- to -end services, including design, development, & testing for customers around the world. With proven expertise across multiple domains such as Consumer Electronics Market, Infotainment, Office Automation, Mobility and Equipment Controls. Vensoft Technologies is managed by Engineers / Professionals possessing significant industrial experience across various application domains and engineering horizontals.Our engineers have expertise across a wide range of technologies, to the engineering efforts of our clients. Leveraging standards based components and investments in dedicated test lab infrastructure, we offer innovative, flexible and cost-effective services and solutions. “We are sure you don’t want to say “This is what I said but not the one I want” when we deliver. So before we start any custom application development project, we always ask our client to define scope of the project. Without having defined scope, you will not be able to measure whether we have satisfied your requirements. It does not mean that it is your duty to give us defined scope. We are here to help you with that. Our experts will be in touch with you during this phase and prepare requirement spects and get it signed from you once you are happy with the same.” Contact Us Mob: 9448847874 Mangalore 4th Floor Vasudev Towers Hotel Satkar Building Near Bus stand BC Road-574219 http://vensofttechnologies.wordpress.com/ http://www.ieeedeveloperslabs.in/ Email: vensoftprojects@yahoo.com Mobile number: 9448847874 8051 PIC16 ARM7 renesas gsm gps zigbee ethernet touchpanel thermal printer webcam image processing communication based m.tech projects

TWO-WAY WIRELESS DATA MESSAGING SYSTEM FOR
RURAL AREAS USING ZIGBEE TECHNOLOGY
ABSTRACT:
A ZIGBEE technology based wireless vehicle identification and driver
authentication system consisting of a central database of authorized vehicles,
ZIGBEE RF Vehicle tags, RF tag Reader and RF tag Writer. ZIGBEE is based on
IEEE 802.15.4 standard for Wireless Personal Area Networks (WPANs) that is
being used in many commercial and research applications today where it has
become an attractive solution for low power and low cost applications. The RF
Tag is placed in a vehicle that will be approaching the entrance of an
establishment, the RF tag reader is used to communicate with the RF tags and the
RF tag writer is used to program or write to the RF tags.
Vehicle identification is performed by reading the serial number in the RF tag and
driver authentication is done by means of a password entered through the RF tag. Both
information are read through the wireless 802.15.4 interface via the RF tag reader and
sent to personal computer through the ZIGBEE. In order to enhance the data security, 128
bit Advance Encryption Standard (AES) was implemented in the ZIGBEE interface.
This paper is based on a prototype development of the proposed system and it
presents hardware and firmware aspects of the design. A vehicle identification device
profile was defined and developed using the Microchip ZIGBEE protocol stack.
Hardware implementation of ZIGBEE RF tags, reader and writer was carried out using
Microchip micro-controller ATMEGA16, Chip on CC2420 RF transceiver and an
inverted F-type PCB antenna which was used with the transceiver. The designed
application functions in the 2.4GHz frequency band. The physical layer of the ZIGBEE
stack is implemented in the CC2420 transceiver and the Microcontroller implements the
other layers including the application layers of the ZIGBEE stack.
This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify
the ac output of secondary of 230/18v step down transformer.
