| dc.description.abstract | Nowadays VoIP plays an important role in communication, and more and more people
use VoIP instead of traditional telephones because of low cost, accessibility and
improved quality. However, one of disadvantages of VoIP is that users have to receive
the Internet calls by headset and microphone, which are attached to a PC. This way
restricts the users’ mobility and doesn’t meet the need of modern users. An innovative
improvement would be to use some existing wireless technology to impart mobility to
VoIP calls. We propose to use Bluetooth due to its widespread availability in already
ubiquitous mobile phone market.
Bluetooth is a short-range communication protocol intended to replace the cables
connecting portable and /or fixed electronic devices. Bluetooth is one of the most
widespread wireless technologies available in most mobile phones available in the
market today because of its low power consumption, low cost and robustness. This
project aims at using Bluetooth enabled mobile phones as wireless headsets for PCs
that run Internet telephony software in order to induce mobility. The project focuses
on investigation and analysis of Bluetooth and related technology for building such a
solution, such as service discovery, redirection, security and fast handover. From the
research done, this thesis proposes mechanisms and design for a prototype that allows
the connection between PCs and Bluetooth enabled mobile phones. The project also
reviews different available alternatives and compares existing solutions.
We believe that since Bluetooth and VoIP become more and more mature, our project
will be applied in people’s daily life soon. And this ideas proposed in this project
would be a convenient and useful extension to already existing Bluetooth server
available on most mobile phones, providing that extra bit of mobility around a
workstation or PC. | en |
