Performance of bluetooth communications in widespread systems / Herwan Shah Mohamad

Nowadays, implementation of the tracking system has become a common issue in modern technology due to the advantages of detecting the location of the object. Things are commonly tracked via follower based next to the implementation of RFID, GPS, and GSM imply strength. This method commonly requires line-of-sight operations and limited coverage for accessing signal strength. In this paper presents a performance of Bluetooth using two Arduino as a Beacon, personal smartphones as an object, Graphical User Interface (GUI) using MIT APP was built in smartphone to display the system accessibility network detection by Bluetooth’s Service Discovery Protocol (SDP). The Bluetooth system performance is observed between two Bluetooth devices using the hardware testbed (Arduino & MIT Apps development) and software simulation (OPNET) and analysed in terms of types, signal strength, with and without wall and separation distance from 0 meter up to 100 meters, which were measured against range, strength, interference, connection establish, through put, packet drop, packet delay and etc. The findings show that the transmission disconnected and drop varies exponentially with the kinds of environment and separation distance. Purpose of this research to check how far and what is the main influence in localization indoor environment. As a result after multiple scenario been done, it could be say that bluetooth for child and object tracking into building it still effective and reliable without much cost to purchase the devices compared with Wi-Fi connection where required to have a SSID and password from the management mall office same goes to the telco for GPRS tracker which is some building the coverage for 3G and 4g is very poor and offline.
