MANET (Mobile Adhoc Networks) is an IETF working group.
From their [http://www.ietf.org/html.charters/manet-charter.html charter]:
- The primary focus of the working group is to develop and evolve MANET routing specification(s) and introduce them to the Internet Standards track. The goal is to support networks scaling up to hundreds of routers. If this proves successful, future work may include development of other protocols to support additional routing functionality. The working group will also serve as a meeting place and forum for those developing and experimenting with MANET approaches. The working group will examine related security issues around MANET. It will consider the intended usage environments, and the threats that are (or are not) meaningful within that environment.
The Chair for the group has a navy.mil email address; you do the math.
