On-Demand BlueTooth: Experience integrating BlueTooth in Connection Diversity
Keyword(s): wireless; TCP/IP; BlueTooth; BNEP; inquiry
Abstract: Using TCP/IP applications between two peers over BlueTooth usually require many manual steps from the user. Our Connection Diversity framework offers mechanisms to automate all these steps. The implementations of Connection Diversity over BlueTooth enables TCP/IP applications to transparently use BlueTooth and smoothly handoff to other link layers. We explain how Connection Diversity interface with BlueTooth and various aspects of the implementation, including the management of connections, discovery, Co-Link and name resolution. We then suggest a few modification of Blue Tooth to improve its suitability for peer to peer applications. We also discuss how to optimise BlueTooth handoffs. This implementation allowed us to test various peer to peer usages models, we report their user friendliness, their performance characteristics and how the design of BlueTooth impacts user experience.
