A challenged network is dened as a network that has one or more of the following characteristics: high end-to-end path latency; end-to-end disconnection meaning a path between a node pair my never exist; limited
Nevertheless, the network might have intermittent connectivity and, accordingly, data communication becomes challenging in such a disjointed network where there is no contemporaneous path between source and destination due to satellites' mobility pattern and given the limitations of range. In this survey,...
Thus, Delay Tolerant (DTN) protocols as a new approach were introduced to store, carry, and forward the data packets when a route is not discovered. In this survey, we consider both DTN and Non-DTN protocols, as CubeSats’ missions may create a connected or disjointed network. The relevant...
