Recent advances in the fields of sensor networks and mobile robotics have provided the means to place monitoring/sensing equipment in an increasingly wide variety of environments - a significant proportion of which can reasonably be expected to lack traditional network connectivity characteristics [5] [8]. Challenged networks, operating under significant sets of constraints in which disconnected paths and long delays are normal events, have come to be known as Delay/Disruption Tolerant Networks (DTN) [2]. Some examples of environments in which DTN techniques may be required include remote or vast domains such as underground, underwater, outer-space, Arctic, and mountainous environments.
