“…This process continues until the message reaches its destination. This model of routing constitutes a significant difference from conventional ad hoc routing, and is usually referred to as encounter-based routing, store-carry-forward routing, or mobility-assisted routing [6], [3], [7]. The names come from the fact that the routing of a message in DTNs has taken the nodal mobility as a critical factor in the decision on whether the message should be forwarded.…”

“…Nonetheless, they are subject to various limitations due to the simplified assumptions related to the nodal mobility scenarios [12], [23], or the utility function presentation [11]. More importantly, the channel capacity and buffer occupancy states have not completely been considered as factors in the derivation of utility functions.…”

Abstract-This paper introduces a novel multi-copy routing protocol, called Predict and Forward (PF), for Delay Tolerant Networks (DTNs), which aims to explore the possibility of taking mobile nodes as message carriers for end-to-end delivery of the messages. With PF, the message forwarding decision is made by manipulating the probability distribution of future intercontact and contact durations based on the network status, including wireless link condition and nodal buffer availability. In particular, PF is based on the observations that the node mobility behavior is semi-deterministic and could be predicted once there is sufficient mobility history information. We implemented the proposed protocol and compared it with a number of existing encounter-based routing approaches in terms of delivery delay, delivery ratio, and the number of transmissions required for message delivery. The simulation results show that the proposed PF outperforms all the counterpart multi-copy encounter-based routing protocols considered in the study.

Summary. Delay tolerant networks (DTNs) are wireless networks in which an end-to-end path for a given node pair can never exist for an extended period. It has been reported as a viable approach in launching multiple message replicas in order to increase message delivery ratio and reduce message delivery delay. This advantage, nonetheless, is at the expense of taking more buer space at each node. The combination of custody and replication entails high buer and bandwidth overhead. This paper investigates a new buer management architecture for epidemic routing in DTNs, which helps each node to make a decision on which message should be forwarded or dropped. The proposed buer manage- Extensive simulation results show that the proposed buer management architecture can achieve superb performance against its counterparts in terms of delivery ratio and delivery delay.
