Bluetooth is a wireless networking technology specifically developed for Personal Area Networking and other short range applications. piconets of up to eight devices can be formed by networking the bluetooth devices together. Here in this network, single device is the master and the rest are slave devices. Several piconets can be interconnected to form a scatternet. This process involves allowing the bridge nodes to operate in multiple piconets by interleaving their membership. Scatternet formation and routing can be considered as the major problems to be addressed in the future of bluetooth networking. The security is another issue of concern. The issues of Bluetooth security and security attacks is also described here. The scope of Bluetooth security is extended to scatternets also.
Introduction
Bluetooth is a widely used standard for wireless Personal Area Networking. The current standard treats the scatternets only briefly. Scatternet formation is the foundation for large scale Bluetooth ad-hoc networks.A distributed algorithm for formation of scatternets is discussed in this article. Piconets are interconnected using common slaves, or bridge nodes. The scheduling of the bridges' participation each piconet is done during during disjoint time-slots. The Bluetooth slot-
ted Time-Division Duplex (TDD) allocation is done here and each slave is addressed in a round-robin fashion and after they have been addressed by a master only, the slaves are permitted to transmit.
