The paper presents techniques to avoid the problem of inter-piconet interference in Bluetooth networks. These techniques aim to reduce the number of piconets created in a Bluetooth networking area. The main advantage of having fewer piconets in a Bluetooth network is the reduction in inter-piconet interference and hence better network performance These techniques are simulated in software called BT-Scatter, which was created specifically to perform Bluetooth scatternet formation simulations. Simulations were run for various randomly generated topologies and the number of piconets created for each of the topologies was collected. Results show that the number of piconets created for a Bluetooth network topology reduces by using the proposed technique.
