Objectives
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
?
•Roaming
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
•Efficiency
