Bluetooth Personal Area Networking
Profile Support with Linux
Maria Bika supervised by Henk Muller
Department of Computer Science, University of Bristol
Bluetooth is a short-range, low-cost wireless technology
which enables seamless interaction between computing
and communication devices. It supports various powerful
usage models for robust ad-hoc networking.
•Experiment with Bluetooth technology under Linux
•Focus on the Ad-Hoc IP Networking capability of Bluetooth
•Evaluate feasibility, performance and reliability of implemented schemes
Using Bluetooth
•LAN/Internet Access
Building a Personal Area Network
•File Transfer, Synchronization
•Creating a Bluetooth Access Point (NAP)
•Adding clients to the Personal Area Network (PAN)
•Integrating network services
Scatternet formation
A Bluetooth PAN consists of
a master and (up to) seven
slaves. A NAP device
forwards the traffic within the
PAN and between the PAN
and other networks. The
clients are called PANUs.
•Feasibility / Topology
•Increasing network capacity
Evaluating Bluetooth PAN Performance
exchanging data
Average throughput for sending
data (in Kbps)
Average throughput for receiving
data (in Kbps)
with the access point
with another PANU
with an Internet host
•Device discovery and connection establishment
•Achieved throughput and network delay
•Improving network performance
Building a Wide Area Wireless Network
Connecting Bluetooth Access Points over:
•Virtual Private Network
Main Issues:
•IP addressing and routing
•Efficiency and performance
Handing off with Bluetooth
•Various implementations were carried out for achieving an efficient scheme
•Advantages and Disadvantages
•Algorithms for improving handoff efficiency
Bluetooth handoff
is invisible to
the IP layer
