Throughput, Energy and Path Length Tradeoffs in Bluetooth Scatternets


Abstract:

In this work we determine an analytical relationship between the average path length
of traffic connections of a Bluetooth scatternet and the overall throughput and power
consumption of the network.

Results obtained implementing this analytical relationship to different
scatternet topologies are presented and discussed. By reducing the hop count
in a scatternet we can achieve better performance in terms of throughput and
power consumption. Therefore, the issue of minimizing the hop count in the
presence of mobility, changing traffic flows and varying interference
receives an important role. In our analysis we also show the impact of the
link quality on the overall throughput.

The obtained results motivate the importance of heuristics aimed at reducing
the communication path length in a scatternet.
