Underlay Fusion of DNS, ARP/ND, and Path Resolution in MANETs

Abstract — Name resolution is a key pillar of the fixed Internet: Without the existing distributed hierarchical infrastructure of name servers, neither eMail (MX records) nor web browsing (all links are expressed with logical names) would be possible anymore. A DNS substitute has to be provided for MANETs which permits, both in isolated network mode as well as in the mesh network case, to use logical names at the application level. In this paper we present a backward compatible dis-tributed and decentralized name resolution scheme for MANETs: The particularity of our scheme is that name resolution, address resolution (IPv4) or neighbor discovery (IPv6) as well as routing path establishment are merged in a single operation. Using the underlay approach of LUNAR we integrate DNS logic at layer 2.5 such that classic Internet applications as well as operating systems settings and libraries do not have to be modified. I
