On the Design and Deployment of RFID Assisted Navigation Systems for VANETs

Major Project , EMB - 02 Dept .Of. ECE, AITS, Hyd


The purpose of project to approach to designing and deploying a RFID assisted navigation system for VANETS (vehicle Adhoc networks).

In our project the estimation of the vehicle

position and its accuracy are also investigated.

MICROCONTROLLER:


FEATURES:

The AT89S52 is a low power, high performance CMOS 8-bit micro computer with 8K bytes of flash programmable and erasable read only memory(PEROM).

The device is manufactured using Atmel’s high density nonvolatile memory technology.

An enhanced CPU core can fetch a single byte from memory every clock cycle


Fully Static Operation: 0 Hz to 33 MHz Three-level Program Memory Lock 256 x 8-bit Internal

RAM 32 Programmable I/O Lines Three 16-bit Timer/Counters Eight Interrupt Sources Programmable Serial Channel 4.0V to 5.5V Operating Range Fast Programming Time

RFID:Defination:

“RFID is a technology that uses electomagnetic waves to identify object ,vehicles ,human in an unique manner”


RFID COMPONENTS:

TagReaderReader antennaControllerHost & software systemCommunication Infrastructure


RFID WORKING:


RFID-ANS MODEL:Each RFID tag should be covered no more than 1

RFID Reader at any instant of time.If the vehicle in the lane the vehicle should able to

read tags that are deployed in the lane.RFID tag should be deployed according to road

navigation requirements.If the vehicle can read a tag at least half of the body of

car should be in the lane where the tag is deployed


LCD:


16*2 LCD

SPECIFICATIONS:


Power supply-5v-dc

Communication-4bit(or)8bit parallel interface

Dimensions in mm- 85length/45width/64inches

Operating temperature- -32 to +158f (or)0 to 70c

EXISTING PROBLEM: GPS having time delay when

compared to RFID communication system . So we are using RFID communication.

PROPOSED SOLUTION:Due to the time delay in GPS system

so that we are using RFID, by that it can track information in few seconds.

ADVANTAGES:


Efficiency RFID can track the information with in few seconds compared

to GPS navigation system

Security RFID technology gives rise to numerous security cocerns

APPLICATIONS: Used in government sectors. Detecting thiefs.Medical applicationsPeople tracking


CONCLUSION:


RFID is a best technology used for any other applications like in vanets, border security, medical and animal identification .
