4. 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

5. SCTP (Cont.) Multi-homing Multiple network connection paths
Redundancy mechanism

6. 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks(6LoWPAN)
Based on IEEE
Characteristics: low data rate, low power
consumption, short distance transmission
Network layer – IPv6
Can speak with TCP/IP without translation

8. 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.
