Short paper: A human mobility pattern-based routing protocol for delay tolerant networks

Delay tolerant networks generally use the epidemic routing protocol, because stable routing paths can hardly be maintained. However, the epidemic scheme leads to much network overheads because the messages are delivered to all the devices. In this paper, we propose an efficient protocol based on the human mobility patterns. In the proposed protocol, a message is delivered to several devices that are expected to deliver well the message to the destination. The proposed protocol relies on the human mobility patterns that contain the regularity. The simulation demonstrates that the proposed protocol reduces the network overheads, while maintaining reasonable delay time.
