  1. Routing Requirements for 6LoWPAN draft-dokaspar-6lowpan-routreq Dominik Kaspar, Eunsook Kim, Myung-Ki Shin, Hyung-Jun Kim

  2. Discussion • Routing Solutions for 6LoWPAN • Possibly, Simplification of MANET protocols • But how? • For which scenarios? • We need a well-defined LoWPAN architecture from which we can derive 6lowpan routing requirements.

  3. Routing Considerations • Special requirements for 6LoWPAN Routing • Power conservation • Low protocol complexity • Tiny device with tiny memory (and/or) tiny processor • VERY High scalability • Common requirements with MANET routing • Ad-hoc routing • Self-organization (self-healing) • Mobility support • Secure connection • etc..

  4. Requirements List General Requirements: • Layer Transparency, Gateways • Robustness despite hibernating nodes • Local and Global Mobility • High Scalability • Secured control messages • Bootstrapping Special to 6LoWPAN: • Reusing MANET Protocols • Adaptation Layer Routing • No PHY frame fragmentation of control messages • 16 bit and 64 bit Addressing • Local repair MAY be omitted • ND without “Hello” Messages (L2-mechanisms) • Low Protocol Complexity • Low Routing State • Short code length • Common requirements or guidelines for 6lowpan routing will lead to design refined routing solutions.

  5. Suggestion • Step 1: • 6Lowpan architecture • Step 2: • Routing Requirement (Guidelines) for LoWPAN routing
