SCTP Stream Control Transmission Protocol (SCTP) SCTP is new reliable and message-oriented transport layer protocol Two powerful functions make SCTP a highly efficient and reliable transmission mechanism Multi-homing Multi-streaming
SCTP (Cont.) Multi-homing Multiple network connection paths Redundancy mechanism data master Internet P1 P1 P2 P2 backup data sender receiver
6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks(6LoWPAN) Based on IEEE 802.15.4 Characteristics: low data rate, low power consumption, short distance transmission Network layer – IPv6 Can speak with TCP/IP without translation

Conclusion and Future work In SCTP multi-homing mechanism, when a master path fails then it will switch to a back up path to continue transmitting data. Master path always in active status but back up path is idle. Design a path conversion algorithm which provides load balance mechanism and automatic path switching which depending on performance of data transmission. Full use of existing resources.
