Delay tolerant network aims to provide the network architecture in environments where end-to-end path may never exist for long duration of time. Furthermore, dynamic topology changes, limited buffer space and non stable connectivity make routing a challenging issue. The research contribution regarding DTN routing protocols can be categorized in to single and multi copy strategies. A single copy strategy makes less use of network resources but suffers from long delay and less delivery probability. Multi copy schemes enjoy better delivery probability and minimum delivery delay at the cost of heavy use of network resource. Moreover, DTN nodes operate under short contact duration and limited transmission bandwidth. Therefore, it is not possible for a node to transmit all messages from its forwarding queue. Hence the order at which the messages are forwarded becomes very vital. In this paper we propose a forwarding queue mode named MinHop. We prove through simulations that the proposed policy performs better then FIFO in terms of delivery probability, overhead, message drop and relay.
