Routing in Delay Tolerant Networks is currently considered as one of the most attracting research areas. While several efforts have led to the introduction of different routing protocols for Delay Tolerant Networks, there are few approaches, which aimed to improve existing protocols. In this paper, the authors present a new algorithm based on the predictability concept since it introduces better resources management in terms of bandwidth, messages delivery compared to other routing algorithms for DTN. They prove by large-scale simulations, the effectiveness of their algorithm in terms of eventually delivered messages, failed transmissions, dropped messages between nodes, buffer time and hop count enhancement.
