Performance of Vehicular Nomadic Node Operation in Realistic Multicellular Wireless Networks

摘要

The need for 5G to adapt the radio access network to the spatial and temporal traffic variations makes the paradigm of moving networks essential. Dynamic network topology and moving cells through vehicular nomadic nodes (NN) will provide coverage extension and capacity improvement on demand as well as achieve reduced capital and operational expenditure when compared to fixed node deployment, such as microcells. Thus, it is of great importance to validate the envisioned performance of this paradigm change in a realistic scenario. To this end, this paper investigates the performance of NN operation in the context of a realistic multicellular wireless network, with the help of site-specific propagation modelling and real geographical databases. The results show that the NN operation can provide clear improvements relative to macrocell-only deployment and also propose the best values for the key systemic parameters that offer the optimum trade-off between throughput and complexity.
