Bluetooth and IEEE 802.11 (Wi-Fi) are two of the
most popular communication standards which define a physical
and a MAC layers for wireless transmissions and operate on 2.4
GHz ISM band. To avoid the rich interference existed in ISM
band, Bluetooth adopts a time-slotted frequency-hopping
spread-spectrum scheme, preventing from the interference for a
long time on specific channel. However, the coexistence of
Bluetooth and Wi-Fi in the neighborhood will degrade the
performances of both networks because the two wireless
technologies cannot negotiate with each other. This paper
presents a novel Bluetooth network construction mechanism
which takes into account the frequencies occupied by WiFi and
thus constructs an efficient Bluetooth network, aiming at
minimizing the interference from Wi-Fi transmissions, when they
coexist in the same space. Performance study reveals that the
proposed connection protocol reduces the interference between
Bluetooth and WiFi and thereby saves the energy of Bluetooth
radio networks.
