In Bluetooth networks, the scatternet is defined as the internetworking of multiple piconets. Currently, Bluetooth standardization does not include the formation issue of scatternet by piconets. The existing formation algorithms of scatternet do not support the features of ad-hoc networks, which cause the performance degradation of systems when the nodes have certain degree of mobility. Therefore, as the formation of scatternet gets complicated, the throughput is lowered and the delay increases due to the inefficient architectural problems. In this paper, we propose the distributed formation scheme for bluetooth in scatternet, in which the nodes are spread out to form scatternet. Simulation results show that the proposed algorithm outperforms the conventional schemes.
