What are the characteristics of optimal Bluetooth scatternets?

The interconnection of piconets in Bluetooth networking has received considerable attention. Whilst a variety of scatternet formation protocols have been proposed, a persistent problem is the comparison of protocol performance, and the quality of Bluetooth network produced. Knowledge of best possible networks is important because this gives a concrete benchmark against which decentralized protocols can be compared. We introduce a new meta-heuristic framework for optimal scatternet formation that operates in a centralised manner. Given device locations, this is capable of exploring the search space of all possible scatternets to find high performance networks, taking into account multiple and tenuous objectives.
