The Bluetooth standard allows to form a scattfrnet network called a piconet consisting of one master and maximum 7 active slaves bluetooth. All communication between slaves is done via the masters. To expand the physical size of the lower class short range Bluetooth networks, the piconets can be joined to form scatternets via Slave-Slave SS bridge a common slave node connected to multiple piconets on a time-sharing basis or Master-Slave MS bridge a link is established between nodes of multiple piconets as shown in Figure 1.
It allows multi-hop communication among Bluetooth enabled devices thus allowing the provision protool a number of new services. Prktocol are many real life applications that implicitly require non uniform deployment of Bluetooth-enabled devices. For instance, in a conference hall, Bluetooth-equipped users are seated in groups. Another application can be smart offices where more Bluetooth-enabled sensors can be placed at certain areas in comparison to others.
It is a 3-phase protocol.
The first phase is of topology discovery where nodes acquire knowledge of its one and two – hop neighbours by forming temporary piconets. The scatternet thus formed does not contain any master-slave bridgewhereas most of the existing works on scatternet formation contains master-slave bridges.
BSFRP divides the nodes into a number of components and each component has a tor. After the protocol terminates the final scatternet is formed with only one leader.
Scatternet formed by joining piconet 1 and 2 by an M-S Bridge and Piconets 1 and 3 byS-S Bridge; the circles represent transmission range of masters. This article is organized as follows. In Section 2 piconet formation in Bluetooth is discussed.
This is followed by brief discussion on related works in Section 3. This is followed by simulation results in Section 5 and Section 6 concludes.
Enhanced AODV routing protocol for Bluetooth scatternet – Semantic Scholar
Bluetooth allows different activity states for the nodes: The standard also allows multiple roles for the same device. A scatetrnet can be a master in one piconet and slave in another at different time instants.
However switching roles imply more latency. Hence an efficient scatternet formation protocol should minimize the roles assigned to the nodes, without losing network connectivity.

It is a distributed protocol that handles node mobility and enables multi-hop communication. BSFRP defines rules for topology discovery, scatternet formation and routing.
Enhanced AODV routing protocol for Bluetooth scatternet
The scatternet phase of the protocol works on the principle of leader election. For routing, AODV is modified to address the constraints of scatternets. It improves the AODV route discovery phase by considering hop count, residual node’s power, and route lifetime for best route selection.
