A routing algorithm based on energy constraint

Delay Tolerant Networks (DTNs) are wireless networks in which at any given time instance, the probability of having a complete path from a source to destination is low due to the intermittent connectivity between nodes. Because of the differences between DTNs and traditional networks, [4]the routing strategies about DTNs can not use the traditional routing methods directly. In the paper, we propose a routing algorithm based on energy constraint. Simulation results showed that ERHR has better performance in energy — consumption than other DTN routing algorithms. ERHR is an effective DTN routing algorithm.
