Abstract:Abstract:Recently, Delay Tolerant Networks (DTNs) have been intensively researched to overcome unstable communication due to the intermittent link connection in wireless communications. In wireless DTNs, to enable continuous connectivity, data are exchanged through intermediate nodes in the path toward the destination node by store-andforward approach. However, since the participating nodes in the network are not fully trusted, a secure data exchange mechanism in the DTNs would be strongly desirable. In this p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
