- This work presents a self-organized message-ferrying algorithm called SOFCOM, which solves the next-hop decision problem in mobility-controlled message ferrying networks. We provide an analytic model for the single-ferry scenario, in which multiple static network nodes require transient connectivity for message exchange. Relaxing the system's state complexity allows us to compare our approach with an optimal guessing oracle, with random-walk, and with a standard TSP-based approach. Based on
the computed candidate solutions, we identify the type and the parameters of the solution space density function in order to judge our algorithm's fitness. We show that SOFCOM can perform as good as a TSP-based approach, although only local decisions are condicted. We discuss important qualitative properties of our algorithm and provide a performance comparison.
