Abstract
Stream control transmission protocol (SCTP) is a transport layer protocol. SCTP is a reliable, message-oriented data transport protocol that supports multiple streams to prevent head-of-line blocking and multihoming for end-to-end network fault-tolerance. A host is multihomed if it can be addressed by multiple IF addresses. SCTP multihoming allow connections, or associations to remain alive even when an endpoint's IF address become unreachable. In a multihomed host there will be at least two IP addresses. SCTP uses one IP for a primary path and the other IF for secondary path. Initially, SCTP uses the primary path for transmission of data. If the primary path fails then the secondary path is chosen for further transmission. Similarly if the secondary path fails then the primary path is chosen for further transmission. Bluetooth Scatternets refers to a collection of Bluetooth piconets. In each piconet one master and atmost seven slaves can be present. Piconets are connected by slave bridges. The proposed system use the multihoming concept of SCTP in Bluetooth Scatternets for effective fault tolerance during data transmission.
