Cricket mote indoor localization system

Abstract

This Final Year Report describes the design, implementation and test of an indoor localization system using Cricket Mote sensors. Unlike the existing commercialized Cricket Mote localization system, the adapted version improves the tracking accuracy by using an active mode approach, rather than using a passive mode where tracking a moving object at high speed is difficult. The new system also eliminates the need to attach a host device when the object is moving by utilizing radio communications between the motes. Furthermore, the mote used as a moving object is installed with multiple US (Ultrasound) sensors to increase the US coverage area and reduce the number of sensors needed to be deployed. The system serves as a test-bed and provides location information to an online centralized database through the web services Java API (Application Programming Interface), which enables other location awareness web applications to easily access the position data.
