This paper proposes a virtual infrastructure-based hierarchical information transmission scheme consisting of two phases, macroscopic transmission and local transmission controls. The macroscopic transmission control builds a hub-node-based virtual infrastructure and then finds the optimal hub route that satisfies the stochastic end-to-end delay constraint. Each node determines whether it belongs to a hub node by itself in a distributed manner. The local transmission control builds a robust local path between hub nodes by using the synchronized redundancy concept; this minimizes the effects of transmission failure by reducing the control traffic overhead and time to reconfigure transmission paths without rediscovery of the transmission path from the source node. Simulations confirmed that, as the network size increased, the performance of the proposed transmission scheme increased in terms of packet delivery ratio and control packet overhead. The scheme can be applied to mobile ad hoc cloud computing systems based on self-organizing vehicular networks or drone networks as a key control.
