Routing decision plays a vital role in delivering a message to its destination in a network, especially in an opportunistic network where connectivity between nodes is unpredictable i.e. intermittent connectivity; routing decision dominates in measuring the network performance parameters. Delay Tolerant Networking (DTN) was proposed to address the technical communication problems in heterogeneous networking ranging from extreme terrestrial environments to planned networks in space. Designing a routing policy for such a network should ideally feature proper handling of the implementation risk and must increase the delivery ratio maintaining a cost of minimum overhead.
