    Abstract

    This paper describes the simulation analysis and hardware implementation of an inexpensive, simple LED based indoor positioning system. Two access systems were considered in this work. The first is a single transmitter and receiver system, while a multiple transmitter and a single receiver represents the second system. Both systems were developed and implemented by the use of low-cost ATMEG 328 microcontrollers. LEDs are used to transmit data which contains the unique location coordinates of the transmitters. Based on these coordinates, we used Multiple LED Estimation Model (MLEM) to track the position of a mobile receiver and report location to a remote observer in real time. Data from LED transmitters were encoded in packets to reduce interference since the transmitters operate at the same frequency and are asynchronous. Results show that root mean square error in tracking can be reduced to about 1 percent of the length of an indoor location.
