A Fast Handoff Scheme For IP over Bluetooth

Recently, the low price and the small size of the mobile device makes a great success in personal mobile communication. A lot of people use a cell phone, PDA, and laptop computer in their daily lives. Bluetooth which enables incompatible devices to communicate with each other over a wireless link can speed up the growth in popularity. BLUEPAC(BLUEtooth Public ACcess) [2] is designed to support IP over Bluetooth and provide users to access to the public network such as the Internet. Our work is motivated by the need for a fast handoff in BLUEPAC. A mobile device experiences frequent handoffs due to the short radius of the piconet which is about 10m. A handoff requires a connection establishment between a mobile device and a new base station which is is a timeconsuming procedure in the frequency hopping system. This situation may cause many connection losses which hurt the network performance as a result. In this paper, we present a new scheme for improving the handoff performance. The ...
