Spray and Routing for Message Delivery in Challenged Networks

In the challenged networks, such as interplanetary networks, satellite networks, military networks and so on, a complete path from the source to the destination does not exist for most of the time. The lack of end-to-end path makes the message delivery a great challenge in these networks. In this paper, we propose the spray and routing message delivery mechanism, which combines the simplicity of epidemic routing and the efficiency of direct routing. We evaluate the performance of Spray and Routing via simulation using the ONE simulator, in comparison with the traditional Epidemic, Prophet and Spray and Waiting protocols. The simulation results show that our method can achieve better performance.
