Meaning "tiny" network, a piconet is a Bluetooth network composed of two or more Bluetooth devices that operate in close proximity on the same channel and frequency hopping sequence. Piconets operate in both ad hoc (peer-to-peer) and infrastructure (central base station) modes of operation.
Masters, Slaves and Scatternets
In a piconet, one device is the master, which establishes the frequency hopping scheme, and there can be up to seven active and 255 inactive slave devices. However, a slave in one piconet can be a master in another, creating a chain of piconets called a "scatternet" that extends the distance between all devices. See Bluetooth.

- Comparison of Bluetooth Interconnection Methods Using BlueProbe
- Many Bluetooth researches are targeted to form efficient scatternets. However, scatternets do not have much popularity in general because many Bluetooth devices do not support scatternet capabilities and high mobility makes it difficult to keep the connectivity. Instead one chooses temporary interconnection of piconets to reduce scatternet formation overhead. To...

- This paper proposes an Adaptive Scheduling Algorithm ASA for Bluetooth scatternets. ASA is adaptive in which the bandwidth allocated on each link or session is dynamically adjusted based on the estimated traffic. ASA integrates both intra-piconet and inter-piconet scheduling to improve the aggregate throughput and delay. ASA prevents the bridge...
