TUTORIAL III
The Bluetooth Technology: Specifications and Performance
Rajeev Shorey and Apurva Kumar
IBM India Research Laboratory
Audience: This tutorial is intended for computer professionals,
telecommunication engineers, researchers, educators, and graduate
students interested in the Bluetooth technology.
Course Description: Bluetooth technology provides a low
cost, low power, and low complexity solution for ad-hoc wireless
connectivity. The technology is capable of connecting a wide variety
of devices like Personal Digital Assistants (PDAs), mobile and cordless
phones, headsets, desktops and notebook PCs, digital cameras, home
appliances, etc. The applications include eliminating cables/ wires
between devices like PCs, printers, modems, projectors, self synchronization
between PDAs and PCs, wireless connection to local area networks
(LANs) through access points and internet through mobile phones,
providing home networking solutions, etc. This tutorial will provide
an overview of Bluetooth technology and its applications. The Bluetooth
system will be introduced and various modes of operation will be
discussed. A description of functionalities of Bluetooth layers
and the protocol specifications will be presented. Various usage
scenarios and the profiles which support them will be explained.
An insight into the performance of Bluetooth based systems will
be provided. Means of evaluating/improving performance of Bluetooth
based systems will be discussed. Key features of an open-source
Bluetooth simulation tool which can be used to evaluate the performance
of applications over Bluetooth will be described. We will provide
an overview of a number of open research problems related to Bluetooth
specifically, and short range wireless in general. Some of the problems
that we will discuss are MAC scheduling with and without low power
modes, performance of TCP/UDP over a Bluetooth piconet and Bluetooth
capacity.
Lecturers: Apurva Kumar received his M.S degree from the
Indian Institute of Technology, New Delhi in 1997. From February,
1997 to August, 1999, he was with Silicon Automation Systems, Bangalore,
where he was involved in wireless systems engineering projects with
Nortel Networks. Since September, 1999, he is working as a Research
Staff Member in IBM India Research Laboratory, New Delhi.
Rajeev Shorey received a Bachelor of Engineering (B.E) in Computer
Science from the department of Computer Science and Automation,
IISc, Bangalore, in 1987. He received the M. S and Ph. D degrees
in Electrical Communication Engineering from the IISc, in 1990 and
1995 respectively. From December, 1995 to February, 1998, he was
with Silicon Automation Systems, Bangalore, where he worked on the
performance modeling and analysis of CDMA networks. Since March,
1998, he is a Research Staff Member in the IBM India Research Laboratory.
Dr. Shorey has numerous papers in international journals and conferences
to his credit. He has more than 9 IBM US patents that are pending
and has been in the technical program committee of several international
conferences in net-working. He is also an adjunct faculty in the
department of Computer Science and Engineering, IIT, New Delhi.
Dr. Shorey is a senior member of the IEEE.
