Accelerating Bluetooth inquiry for personal area networks

چکیده

The recent industry standard Bluetooth promises low cost replacement of communication cabling with moderate symbol-rate, short-range wireless links. The same specification also addresses the establishment of point-to-multipoint piconets and the interconnection of several of these piconets into scatternets, enabling Bluetooth to be used as a technology for realizing personal area networks. Establishing Bluetooth piconets requires nodes to discover each other by completing an inquiry phase. This paper investigates the inquiry phase; shows the shortcomings of the current inquiry procedure in multi node – PAN scenarios, and outlines and analyses a backwards Bluetooth compliant modification to accelerate Bluetooth inquiry. Extensive simulations comparing the original and the proposed Bluetooth inquiry schemes show improvements of more than an order of magnitude in device discovery times.

Priority Based Polling and Scheduling Algorithm for Intrapiconets in Bluetooth

The trend of dynamically interconnecting the personal devices that people carry with them has led to the introduction of personal area networks (PANs) and personal networks (PNs). The Bluetooth wireless access technology is believed to be a potential enabler of PANs and PNs. This dissertation focuses on Bluetooth intrapiconet scheduling (also referred to as Bluetooth polling) that helps in maki...

Autoconfiguration and Self-management of Personal Area Networks: a New Framework

In the Beyond 3G vision, users will carry multiple devices forming cooperative networks, known as Personal Area Networks. Some of the existing technologies enable this type of networks, such as Bluetooth or IEEE 802.15.4, but a unified framework capable of self-organizing and deploying them dynamically still has to be defined. These networks are also envisioned to be connecting dynamically to t...
