  1. Pedro M. Ruiz Francisco J. Ros March, 2006 Dallas, USA 65th IETF Extensible Manet Auto-configuration Protocol (EMAP)draft-ros-autoconf-emap-02.txt

  2. 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 2

  3. 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) 3

  4. 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 4
