UAV data delivery and routing optimization in Piggyback Network

抄録

The Piggyback Network has been proposed as one of the technologies to enable Beyond 5G society. The Piggyback Network provides a high-speed data transfer system with frequency radio, such as millimeter-wave (mmW) links and Store-Carry-Forward (SCF) based communication among multiple autonomous mobilities. Communicating with mmW enables high-speed and large-capacity data transfers. Autonomous mobilities include service robots, cars, and unmanned aerial vehicles (UAV). Simple calculations demonstrated the end-to-end throughput performance when a single mobility unit transfers a single piece of data. This paper considers expansion to handle multiple mobilities and data. To realize this data transfer system, we require data delivery assignment to autonomous mobility and route optimization. We propose local search algorithm for minimizing cost value based on the total time required for data to be delivered to the destination. This paper evaluates the data transfer performance of the Piggyback Network by UAVs in a large-scale field. If multiple data and delivery routes are appropriately assigned to multiple mobilities that can communicate at 10Gbps and move at 100km/h, the Piggyback Network can transfer 100GB of data within approximately 2 min, which corresponds to a throughput of approximately 3000Mbps. If the data size is 1000GB and mobilities can move at 10Gbps, data transfer is completed in approximately 4 min, which achieves approximately 30000Mbps, faster than 5G and long term evolution (LTE) networks.
