To find out the delay distribution in a disruption tolerant network between the nodes when there are randomly distributed several numbers of replications of packets on each node. This delay distribution function can help us with a guideline on how to set the lifetime of a message. As the number of replicas on the nodes increases the delay increases. Up to our best knowledge it is the first time ever work has been done on simulating the delay distribution environment using the replicas in for finding the delay in DTN. With different number of nodes in a network where each node consists of several number of replicas of the same packet the delay difference is obtained and has been compared with the network consisting of a fewer more number of nodes.
