PERM: Performance Evaluated Routing Mechanism in Delay Tolerant Networks

The Delay Tolerant Networks (DTNs) are special networks wherein no two nodes share any continuous or dedicated path. Nodes go up and down various times a day and do not behave in any prescribed or probabilistic manner. In such a scenario message flooding seems the easiest solution but it is a costly affair. Network connections being so abrupt, the chance of delivery of a message gets affected hugely by the strategy we use to flood the messages. Nevertheless we can try to find a method to this madness so that maximum messages get delivered by using as less message replications as possible. In this paper we propose a new system which will facilitate in more messages being delivered by trying to utilize the behavioral patterns of the nodes present in the network in an unbiased manner.
