Overview

• Protocol for local and global auto-configuration
  in IPv4/v6 manets
• Local allocation of unique IP addresses for
  intra-manet communications (MANET-local
  addresses)
• Global allocation of unique globally routable IP
  addresses and (at least) a route to the Internet
  for external communications
• Extends the ideas of previous IETF
  internet-drafts
• Tries to fulfill two main objectives
• Extensibility
• Low overhead
• Can be integrated within an ad hoc routing
  protocol
• The protocol can be used as a general service
  discovery mechanism
• New services can be easily added in the future

Basic additional features

• Local auto-configuration
• MANET-DAD procedure (request/reply)
• May use information of the routing protocol to
  detect/avoid duplicates
• Global auto-configuration
• Internet-Gateways (IGWs) may operate either
  proactively, reactively, or in a hybrid way
• An adaptive algorithm based on the distance to
  the sources is recommended
• Routes to the IGWs are created
• Messages can be combined to reduce overhead
• Additional features
• DNS discovery
• Nodes can work as intermediate proxies (P bit)

Further work

• Change MANET-DAD to a conflict resolution
  approach
• Assume the uniqueness of the auto-configured
  address
• Solve the conflict when it is detected
• Format and scope of MANET-local addresses
• Unique Global Addresses with a reserved Global
  ID?
• Determine when proxying is worthwhile
• Integration within routing protocols, is there
  any consensus about it?
• Use of SMF...
• to forward flooded messages conflicts with the
  use of proxies
• to detect duplicated packets currently the
  protocol uses caches, but this could be an
  alternative
• Secure operation of the protocol
