Modeling and evaluation of Bluetooth MAC protocol

The emergence of Bluetooth as a default radio interface allows handheld electronic devices to be instantly interconnected into ad hoc networks. These short range ad-hoc wireless networks, called piconets, operate in the unlicensed 2.45 Ghz ISM (Industrial-Scientific-Medical) band where up to eight devices may be used to configure single or overlapping piconets. This creates interference on the device from other devices operating in the same frequency band including microwaves and devices enabling various wireless LAN standards. This paper uses a signal capture model to study piconet MAC performance. Furthermore, simulations are used to validate the throughput obtained from this model. These results reveal important performance implications of the effect of interpiconet interference on throughput.
