Bluetooth Personal Area Networking Profile Support with Linux Maria Bika supervised by Henk Muller Department of Computer Science, University of Bristol ? 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 Evaluating Bluetooth PAN Performance PANU exchanging data Average throughput for sending data (in Kbps) Average throughput for receiving data (in Kbps) with the access point 612.8 600.7 with another PANU 215.9 195.4 with an Internet host 340.3 320.5 •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 •Bluetooth ? Main Issues: •Topology •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
