Summary
• This presentation provides some of tips for following perspectives– To show use cases to share what L2R
protocol will be required– Proposing preliminary ideas regarding
what functionalities will be required
Note: This is really preliminary and does not cover all.

Ad-hoc data collection
What mesh will be required for FAN?• Mainly, data collection from many nodes in FAN and control of many nodes in FAN
from the outer server – Many to one and One to many routing protocol will be suitable• Ad-hoc data collection in the field area may be required in some use cases –
Reactive P2P routing may be required • Covering 1000+ nodes within one PAN and expected to interwork• Low power technology may be required in environmental monitoring or gas metering.

An example scenario for managing FAN• Network should be configurable and workable automatically.• Less cost repairing process will be required when the network has problem.• After the problem has gone, network should be reformed (maybe to almost
original ) to reduce the load.

Non IPprotocol
Multiple protocols of upper layer
• Ether allows multiple protocols to work on it. L2R may need to do like it. To distinguish the protocols, it may need to hire a Protocol ID.
IPv6

L2R mesh
IEEE802.15.4
TCP UDP
MeshManagement This can be vendor specific or
be defined in the standard. But we should consider so that
multiple protocols works over L2R mesh at least .
Protocol ID?

Other required stuffs
• To make it work in the large network– Enforcement of reliability
• Enhancement of hop-by-hop retransmission to reduce the E2E retransmission– Scattering the Joining timing when the whole network restarts
• Scalability– Nodes density, network size etc.
• Sleeping routers and sleeping end nodes for the environmental monitoring
• Management of flooding, multicasting– Timing, grouping etc.
• Congestion avoidance, flow control• Security• Priority of frames• Others
– Considering scalability of hardware resources to network size
