OUTLINE BMX@WBMv3

• Background
• Propagating Reachability Information:
  • learning about other nodes exitence and profile

  • Metrics: identifying best routes
    (Distributed Hashes and Individual IDentifiers)

• Demonstration
  

  • Realtime, emulating a ~40 nodes virtual mesh network

  • configurable packet loss and delay
    - experiment demands from the audience
    
    

  (sorry for technical nature of this talk)

BACKGROUND BMX@WBMv3

• BMX (acronym for B.a.t.M.a.n - eXperimental)
• historically: experimental branch for testing new features for BATMAN
  • more configuration options, new mechanisms, ...
  • always executable as # batmand ath0
• generation III-IV temporary compatible to BATMAN

  • BMX v0.3 evolved towards an independent routing protocol:
    

    • some communities selected BMX for meshinh

      • (LugroMesh, GraciaSensefills, FFLeipzig, FFDresden, Nicaragua,..)

    • larges BATMAN/BMX network in Leipzig (~200 nodes) is BMX
  • Winner of Merakas' Routing Protocol Evalutation is BMX (comparing OLSR, BATMAN, BMX)
  • Since WBMv3 BMX v0.4 implementation...

Propagating Reachability Information

• Motivation and Ideas

Propagating Reachability Information

Motivation for redesign of propagation mechanism

• (triggered by IPv6 support requests)

1. Idea: Use Hash instead of constant description

2. Idea: Use Individual Identifier (IID) instead of Hash

Metric

Demonstration
