Delay Tolerant Network(DTN) is a wireless network in which there will be no connectivity exists between source and destination in a given time. Due to the absence of fully connected path between the source and destination, there will be a problem to route a packet from one node to another in DTN .Similarity based techniques relying on contact patterns among nodes provide routing in DTN provides high delivery success rate. This paper is discussing about a PRICE scheme, a greedy forwarding scheme for DTNs that combines geographic oriented forwarding with contact based forwarding by relaying packets according to predictable patterns of location and contacts. Here a throw box is also introduced in the network to store information about frequent contacts and locations used by the network. The simulation result outperforms all other routing solution in terms of cost/delivery success ratio.
