Delivery of the application data in delay tolerant network relies on the custody transfer provided by the node storage. Fast release of the occupied node storage is significant for reducing congestion and enhancing network capacity. Studies have shown that the storage efficiency is affected by the size of packet at various network layers. We propose a storage management scheme based on cross-layer packet size optimization, OSUS. OSUS can dynamically adjust Bundle size and the transport layer frame size to maximize the node storage utilization. Simulation results show that, compared with traditional schemes where joint optimization algorithms are not adopted, OSUS can bring 15% improvement on average in the node storage utilization.
