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

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 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
