Updates since Chicago

• More co-authors )
• Deployment Scenarios
• Simple PANs
• Added more example usage such as sensors network
• PMRs in Vehicles
• Added the case where PAN merges with Car network
• Requirements and Desired Features
• Break into requirements and desired features

3
Quick Recap Scenarios

• Simple PANs
• PMR provides internet connections to nodes in PAN
• An MNN may leave the PAN (and continue to use
  same address)
• An MNN may become a PMR and vice versa
• PMRs in Vehicles
• PMR docks into Car
• Distinct network nested NEMO
• Merged network Multi-Router NEMO
• Residence Network
• HA is a set-top box at home (literally)
• Most of these scenarios are not new
• Presented by Vijay a year ago
• Found in MANEMO/Autoconf discussions

Requirements

• Req1 Unmodified LFN
• A route optimization solution MUST operate even
  when LFNs are unmodified
• LFNs are simple IPv6 devices that cannot be
  easily patched or updated
• Req2 Low Processing Load
• A route optimization solution MUST NOT increase
  the processing load of MR significantly
• PMR are battery powered devices
• Req3 Security
• A route optimization solution MUST NOT expose the
  mobile network to additional security threats
• Not possible for attackers to claim ownership of
  mobile network prefix
• Not any more susceptible to DoS attack (eg. force
  MR to send huge amount of signaling packets or
  maintain large number of signaling states)

5
Desired Features

• Des1 MR-to-MR RO
• Most deployments scenarios we envisage are
  communications between PANs
• Des2 Nested NEMO RO
• When the PAN goes into a vehicle/vessel, nested
  NEMO is formed
• Des3 Intra-NEMO RO
• When the PAN enters the vehicle network, some
  form of communications between the nodes from the
  two networks may occur

6
Questions for WG

• Are these scenarios what the WG expects?
• Similar scenarios we overlooked?
• Any scenarios that are not useful at all?
• Should we explore further into
• PANs in vehicle/vessel scenario?
• MNNs breaking off from PAN?

7
Questions for WG

• Are these requirements reasonable?
• Too stringent?
• Too general?
• Any requirements that we missed?

8
Questions for WG

• Should we adopt this as WG work item for A.5(3)?
• Adopting this does not mean it is completed
• it only means we work on it as a WG
• There is no competing contribution for this WG
  item
