Design and Implementation of Energy efficient MAC Layer for Indoor Real Time Localization Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Positioning is a technique that is used to locate mobile devices in real-time or near real time. As GPS system can’t truck movable objects accurately in indoor environment there have to be another method that should be designed and implemented? In this paper it is presented the design and implementation of a Medium Access control (MAC) that relies on ultra wide band (IEEE 802.15.4a) technology and it is also described why IEEE 802.15.4a has been chosen. The system built uses time difference of arrivals (TDOA) technique to estimate the position of the movable object. Through thorough evaluation the mobile device can be tracked with a deviation of ±1.1m, but it assumed if all devices are synchronized effectively this accuracy can be improved.
