Delay and/or Disruption-Tolerant Networking (DTN) is a novel communication prototype that can span across multiple networks and deal with unpredicted conditions in the Internet model. Pocket Switched Networks (PSN) are delay tolerant networks with hand held devices. Nodes in a PSN make use of a store-carry-and-forward paradigm to communicate along with themselves. The routing protocols performances that have been developed for DTN based on the movement pattern of the nodes. We propose a Human Mobility based Spray & Wait Routing protocol (HMSaW). This protocol makes use of truncated power law distribution of pause time and flight length of human mobility to smartly forward data in DTN and PSN. Simulation results show that the proposed HMSaW shows better delivery ratio and the communication overhead, with marginal reduction in average delay compared to existing PROPHET and Spray & Wait Routing protocol.
