Recently proposed Delay Tolerant Networking (DTN) architecture aims at supporting efficient message-based communication over intermittent networks. Delay Tolerant Networks (DTNs) are generally characterized by long and variable delays due to intermittent connectivity. This lack of connectivity makes most of the existing routing protocols in WSNs not applicable in DTNs (the performance of such networks depends on connectivity and mobility of some nodes). The authors propose in this paper a new routing mechanism for a DTN using WSN nodes for localization or traceability applications.
