Abstract
A Bluetooth ad hoc network can be formed by interconnecting piconets into scatternets.
The constraints and properties of Bluetooth scatternets present special challenges in forming an ad hoc
network efficiently. This paper, the research contributions in this arena are brought together, to give an
overview of the state-of-the-art.
Simply stated, Bluetooth is a wireless communication protocol. Since it's a communication protocol, you
can use Bluetooth to communicate to other Bluetooth-enabled devices. In this sense, Bluetooth is like any
other communication protocol that you use every day, such as HTTP, FTP, SMTP, or IMAP. Bluetooth has
a client-server architecture; the one that initiates the connection is the client, and the one who receives the
connection is the server. Bluetooth is a great protocol for wireless communication because it's capable of
transmitting data at nearly 1MB/s, while consuming 1/100th of the power of Wi-Fi. We discuss criteria for
different types of scatternets and establish general models of scatternet topologies. Then we review the
state-of-the-art approaches with respect to Bluetooth scatternet formation and contrast them.
