A practical performance analysis of low-cost sensors for indoor localization of multi-node systems

In this work, we conducted a study for choosing suitable sensors for indoor localization of multi-node systems. This study is used to compare the performance of the cheapest and most appropriate sensors for measuring the distances among nodes at indoor environments which are the ultrasonic and the infrared sensors. Practical circuits for these sensor types are built and tested in an environment which has cylindrical nodes with different colors. These experiments are repeated for different angles of view to produce a complete analysis for the performance of these sensors.
