How to cite the BATMAN routing protocol in a research paper?

Subject: How to cite the BATMAN routing protocol in a research paper? Hi, I cannot find a proper citation for the BATMAN routing protocol. The citations I could find were:

A. Neumann, C. Aichele, M. Lindner, and S. Wunderlich, “Better approach to mobile ad-hoc networking (B.A.T.M.A.N.)," IETF Draft, 2008 [Online] R. Sanchez-Iborra, M. -D. Cano and J. Garcia-Haro, "Performance Evaluation of BATMAN Routing Protocol for VoIP Services: A QoE Perspective," in IEEE Transactions on Wireless Communications, Sept. 2014

which are incomplete and outdated. Is there any references I can use for citing BATMAN IV or BATMAN V in a research paper? It would help me a lot.
