Analysis of Bluetooth Protocol in Presence of Bursty Traffic

Abstract

Bluetooth (BT) technology through its considerable functionality and flexibility is incorporated inmany modern personal electronic devices, offering reliable and sufficient wireless connectivity. On the other hand, the new generation of cellular communication systems while providing wide coverage and mobility are unable to offer a cost effective interconnection of so many personal devices. Web browsing, e-mail, chat, gaming, voice and video are just a part of the services inquired from the modern communication systems. Here web-browsing performance of BT enabled devices is treated through analytical, numerical and simulation analysis. The foreseen scenarios assume that a personal device (PDA, Laptop) is connected to Internet through phone or WLAN, using BT as a connecting technology. For the purpose of the examination, a new generic simulation-based analysis and precise performance evaluation method is introduced. The method uses the formal language representation of the analyzed protocol specification, hereafter called behavior model. The behavior model code obtained from the IEEE 802.15 standardization committee has been assimilated and upgraded into a novel, comprehensive and standalone Specification and Description Language (SDL) - based simulator. A WWW traffic generator was created in accordance with the 3GPP specifications. The Bluetooth protocol performance was assessed in network scenarios with different traffic amounts and characteristics. This new concept is flexible and versatile, and can be easily performed for any other kind of traffic, or any other communication standard. The analysis show that the simulation-based results match with the analytical and numerical calculated values, remarkably.
