Survey on Routing in Pocket Switched Network

Pocket switched Network (PSN) is an emerging research magnet that has been attracting re-searchers. This paper provides an introduction to PSN and covers some of its basic features and challenges. Continuous connectivity is difficult in infrastructure independent communication. In this paper, we will see how PSN provides an effective alternative. We also explain some routing protocols that can be incorporated for effective data forwarding. This paper also discusses possi-ble applications and areas where PSN can be effectively used and some ideas that may foster fu-ture research in PSN routing
