Searching for Content in Mobile DTNs

Delay-Tolerant Networking (DTN) provides a platform for applications in environments where end-to-end paths may be highly unreliable or do not exist at all. In many applications such as distributed wikis or photo sharing, users need to be able to find content even when they do not know an unambiguous identifier. In order do bring these applications to the domain of DTNs, a search scheme is required that works despite the unreliable network conditions. In this paper, the authors introduce a search scheme that makes no assumptions about the underlying routing protocols and the format of search requests.
