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

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
