To solve this, small cells are deployed within the vehicles to improve the Quality of Service (QoS). These small cells called moving small cell access points (MSAPs), however, suffer from backhaul issues since they would have to send a huge amount of data to the core network. To solve the backhaul problem, cloud radio access network (CRAN) along with the millimeter wave (mmwave) can be a viable solution for moving vehicles. However, in order to realize its potential benefits, an effective remote radio head (RRH) deployment strategy and the resource-efficient allocation are needed. In this paper, we investigate the placement of RRH alongside a railway track; then, for the placed RRH, a joint time slot and power allocation problem are formulated with an objective of maximizing the resource efficiency (RE) of the MSAP backhaul network. An optimal Branch and Bound Algorithm (BnBA) is proposed for the constituted non-linear integer problem, and the effects of changing various model parameters are investigated. The simulation results show that our proposed algorithm deviates 52% of the sub-optimal result. © 2013 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.BackhaulCRANEnergy efficiencyFronthaulMmwaveMoving small cellsResource efficiencyRRHSpectral efficiencyBranch and bound methodCellsCytologyMillimeter wavesProblem solvingQuality of serviceRadio access networksVehiclesResource efficienciesSmall cellsSpectral efficienciesEnergy efficiencyArticleCopyright : Copyright : 2013 IEEE.
