| Summary: | In this modern life, with the prosperous economy we are experiencing, most people own at least one car. Cars have been used widely as a mean of our daily transportation to help us commute from one place to another. As people are becoming so involved with their hectic schedule, sometimes they could not remember where they have parked their cars. Thus, this project is done to help the car owner to locate the distance of the car from his current location. The project uses the half-duplex communication between two units of transceivers, MOBILE unit and FIXED unit to provide the location of the car. The principle of RFID is applied in this project by assigning each unit with unique ID number. The FIXED unit is placed inside the car while the MOBILE unit is kept by the owner. The latter unit does the computation of the location estimation based on the signal it received from the FIXED unit. The estimation of location is done based on the received signal strength formulation. The free space path loss has been assumed. From this received signal strength which is also equivalent to R V 2 , the inverse proportionality of voltage level and distance is used in the calculation. The accuracy of the system is found to be in the range of 0.0m to 50.0m. The accuracy is found to degrade with the further the distance is. The large number is due to the limitation of the formulation used. The system is able to detect the location of the car within 250m radius |
