Abstract

The pheromone can be used for target tracking and, consequently, for packet forwarding to the destination node in delay-tolerant networking. In this study, an initiative community model is proposed by simulating pheromone production and diffusion, which contains all of the nodes that can receive the core node pheromone. We can set the distance of the edge node to the core to be less than five hops by establishing the appropriate spread coefficient ω . Packet forwarding is then converted into the process of tracing the pheromone of the destination node. A set of simulation results shows that the proposed initiative community model can effectively increase the delivery ratio and reduce delay when the community structure is relatively stable.
