The tremendous increase in wireless devices and user mobility has ultimately resulted in a new set of networking challenges that previously did not exist. Some of these challenges include large delays, intermittent connectivity and most importantly, the absence of an end-to-end path from sources to destinations. Networks characterized by one or more of these challenges are called Delay Tolerant Networks (DTNs). Researchers have studied DTNs with a major focus on routing issues in such extreme environments. As a result, this paper shifts this focus towards addressing and studying transport layer issues in extreme networking environments. The paper particularly concentrates on investigating and comparing several reliability approaches in a specific category of DTNs known as Delay Tolerant Mobile Networks (DTMNs).
