ABSTRACT: Indoor organization user
activity’s (UA) direction detection monitoring system and also emergency
prediction are major challenging tasks in the field of the typical body sensor
and indoorfixed sensor networks.
In this paper, indoor UA based direction detection monitoring system is
achieved by the combination of both the orientation sensor and Bluetooth Low
Energy (BLE) in user’s smartphones belonging to the Internet of Things (IoT).
The orientation sensor senses theactual
orientation of the user and BLE transmits the sensed BLE signals to monitoring
system using star topology in IoT. In monitoring system, classification
algorithm is used to identify the directions of the smartphone users. The
emergency situation of the user is also predicted based onsignal variation instantly in real
time. Theuser activity’ssignals are captured using LabVIEWtoolkit then applied tovariousclassification algorithmssuch asRF—91.42%, Ibk—90.55%, j48—85.61%, K*—73.54% are the results
obtained. An average of 85% was obtained in all the classifi- cation
algorithims indicating the consistency and accuracy in detecting the directions
of the users.RF was found to be
the best among all the classification algorithms.IoT enabled devices have highdemand in near coming future, moreover
smartphones users increase day by day, hence implementing and maintaining the
above said system would be much easier and cheaper compared to other
conventional networks.
