The concept of Delay Tolerant Networks (DTNs) are proposed to facilitate communication in challenged mobile wireless networks using the Store-Carry-Forward (SCF) routing behavior. In this paper, the authors' motivation is to take advantage of geographic routing since it routes message without the knowledge about network topology by using real-time location information, overcoming the challenge of large network topology variation in DTNs. Different from traditional geographic algorithms, their approach only adopts history geographic information due to the difficulty to obtain the real-time location of destination, suffering from sparse network density and high mobility.
