Dynamic Segmented Network Coding for Reliable Data Dissemination in Delay Tolerant Networks

Free registration required

Executive Summary

Delay/Disruption Tolerant Network (DTN) differs from the conventional networks in that it has no continuous or contemporaneous connections among wireless nodes. Its inherent characteristic of intermittent connections makes existing routing solutions hardly to be applied directly. Epidemic routing using random linear network coding has been studied and proved as an efficient way for delivering small amount of data. To their best knowledge, the authors are the first to study high performance reliable transmission for bulk or stream-like data in DTNs.
