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

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

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)

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
