The objective of routing protocols in mobile ad hoc is to let nodes to communicate in the absence of network infrastructure using wireless devices. Although powerful to changes to network topologies, current routing protocols suffer from the issue of assuming the existence of a connected path from the origin node to the destination one. However, in today's networks this is not necessary the case. This is due to power limitations, the need for wireless networks with short-range, and the broad physical environment where ad hoc networks must be established. When fully connect paths between pairs of nodes are not always exist, the network is called delay tolerant. This paper presents a new method for routing in delay tolerant networks (DTN). The proposed routing technique is based on path perdition to decide which node is more likely to deliver a message. The path perdition is done using recent locations visited by the node.
