Since the 1990’s, the IETF has become engaged in ad hoc networking, as evident through the MANET working group (routing in MANETs), the AUTOCONF working group (autoconfiguration in MANETs). the OSPF working group which is discussing including ad hoc routing into the OSPF protocol suite - and through activities in the research branch of the IETF (called the IRTF), where the routing research group has ad hoc network systems among its topics.
