               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.
        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..
                Requirements List
General Requirements:                   Special to 6LoWPAN:
 Layer Transparency, Gateways           Reusing MANET Protocols
                                         Adaptation Layer Routing
 Robustness despite hibernating
  nodes                                  No PHY frame fragmentation
                                          of control messages
 Local and Global Mobility
                                         16 bit and 64 bit Addressing
 High Scalability                       Local repair MAY be omitted
 Secured control messages               ND without “Hello” Messages
 Bootstrapping                           (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.
               Suggestion
 Step 1:
  – 6Lowpan architecture
 Step 2:
  – Routing Requirement (Guidelines) for
    LoWPAN routing
