Presentation Transcript

  1. AODV status update • Changes in draft …-10 • Progress towards Experimental RFC • Implementer’s mailing list • Interoperability testing • Futures workshop

  2. Changes since draft …-09 • Reorganized text so that: • Incoming messages change routing information • Outgoing messages utilize information from route table • Affected: RERR, RREP • Specified that sequence numbers are to be compared as signed ints • Changed terminology to replace “FLOODING_ID” by “RREQ_ID”, since the exact meaning of what “flooding” means is up for discussion now • Clarified that RREQs do not have to be retransmitted over every network interface, depending upon type of medium and domain of ad hoc coverage.

  3. Progress towards Experimental RFC • Very good but late comments received from Yih-Chun Hu • Good but late comment received from Manel Guerrero Zapata • should a node remember its sequence number across reboots • Excellent comments received from Bill Fenner and Alex Zinin • All of these comments will be resolved in a new draft version of AODV to be produced before April. Discussion should continue on the mailing list; I will try to send text tonight or tomorrow with proposed resolutions • No changes in packet formats will be needed. There are two egregious mistakes in draft …-10 that need to be fixed right away • missing RREQ_RETRIES definition (should be 2) • RREQ_IDs should be stored for PATH_DISCOVERY_TIME, not PATH_TRAVERSAL_TIME

  4. AODV Interoperability testing • Starts next week with 7 different implementations from different organizations • Implementers mailing list (currently almost 100 members): • aodvimpl-public@lists.sourceforge.net • https://lists.sourceforge.net/lists/listinfo/aodvimpl-public • Linux freeware implementations (forgot the URL ) • Possibly AODV-6 release upcoming (Ryuji Wakikawa)

  5. AODV workshop • Held immediately preceding MobiHOC 2002 in Lausanne, Switzerland • Intended for anyone who wants to provide vision for the future evolution of AODV • progress towards Proposed Standard • QoS extensions • Multipath (very encouraging results from Samir Das) • Flooding backbone • Multicast • Interoperability with Mobile IP{,v6} • Service Location • Any other business • Progress of Globalv6 and Globalv4 draft
