DTN Neighbor Discovery Protocol Challenge
February 11, 2015

This is the 5th challenge in NASA's DTN challenge series!  This challenge launched on February 5th on TopCoder.com and includes multiple contests over 5 months and will award over $50,000.  The goal of this challenge is to update Disruption Tolerant Networking (DTN) "ION" implementation so that it includes IP Neighbor Discovery (IPND).   IPND is a method for otherwise oblivious nodes to learn of the existence, availability, and addresses of other DTN participants. IPND both sends and listens for small IP UDP announcement beacons that are addressed to an IP unicast, multicast, or broadcast address to discover specified remote neighbors, or unspecified local neighbors in the network topology.   Other DTN implementations, such as DTN2 and IBR, already support IPND. We now need to updated DTN ION to enable neighbor discovery capabilities as well. Neighbor discovery is also needed to enable future dynamic routing capability for the ION DTN implementation.   This challenge will:

  • Fully implement IPND within the DTN ION implementation 
  • Develop a test plan and test for IPND specification compliance 
  • Provide documentation on how to configure and use the ION IPND capability 
  • Develop code that can be cleanly integrated into the ION, employing the same coding languages, idioms, etc.
