Implementation of the DELTA object tracking algorithm on the ESB sensor nodes

Event tracking is one of the basic tasks of sensor networks. An intensity-based event localization algorithm was developed at the University of Bern [1]. The inaccuracy of the measurements and resource limitations in terms of energy consumption, storage capacity, processing and transmitting time make a real world implementation of this algorithm a challenging and exciting task. In this internship we investigated the real world feasibility and performance of this distributed object localization and tracking algorithm DELTA that depends on the light sensor readings. Some improvements have been made to the original DELTA algorithm to tailor it to the ESB hardware from Scatterweb [2]. Finally, evaluations and comparisons of different versions of DELTA as well as of a reference algorithm have been done.
