Mutual interference in a Bluetooth Scatternet under different environmental conditions

Wireless Personal Area Networks (WPANs) are becoming popular with mobile professionals. Bluetooth is a Wireless Protocol proposed by the Bluetooth SIG (Special Interest Group). Bluetooth allows a user to create a WPAN just by inserting a chip into a mobile device. Such devices are called Bluetooth enabled devices. The market for Bluetooth enabled devices is going to boom in the coming few years. For this reason, it is important to analyze the performance of a Bluetooth network in proximity to other Bluetooth networks. Important issues addressed by such analysis include data security and interference caused by other Bluetooth devices and non-Bluetooth devices. The objective of this research is to evaluate the performance of a Bluetooth network in the presence of interference caused by neighboring Bluetooth networks. This is called mutual interference. The simulation is done with consideration of different packet lengths, where packet lengths are distributed geometrically. The research also considers the near-far effect on the throughput of a Bluetooth unit. The effect of environmental conditions on the performance of Bluetooth Scatternet is also examined.
