“…This paper extends our previous work [6,7] by considering the case of a multiple users scenario, operating in a dense HetNet equipped with MCC and MEC technologies. The problem of radio resource and data transmission strategy in such network is then formulated as a combinatorial optimisation problem, and solved using an ant colony optimisation (ACO)-based energy-aware algorithm consisting of a data transmission management scheme, a physical resource blocks (PRBs)/bandwidth allocation scheme, and a data split multiple UEs algorithm (DSMU).…”

“…In our earlier work [6, 7], we have investigated the problem of mobile cloud storage for big data transmission, with the goal to minimise the latency while intelligently exploiting the overlapping nature of a dense 5G wireless network to expedite the big data transmissions from a mobile device to the MEC. In this sense, the solution proposed in [6] was to divide the big data file into multiple chunks along with two data correction syndromes and to concurrently transmit them over the available data paths.…”

“…In this sense, the solution proposed in [6] was to divide the big data file into multiple chunks along with two data correction syndromes and to concurrently transmit them over the available data paths. This solution was further improved in [7] by considering that the size of data chunks is proportional to the capacity of the data link used for transmission, and then by designing an error correction method to deal with the eventual errors that might have occurred during the transmission of data packets.…”

This study formulates the problem of radio resource and data transmission strategy in a dense HetNet enhanced with mobile cloud computing and mobile edge computing technologies as a combinatorial optimisation problem. An ant colony optimisation (ACO)-based energy-aware algorithm is proposed as solution approach, which consists of a data transmission management scheme and a physical resource blocks/bandwidth allocation scheme. Simulation results show that compared with baseline approaches [(greedy and data split multiple user equipment (UEs) algorithms]), the proposed ACO-based algorithm achieves: (i) about 99% of reduction in terms of transmission delay under varying data file sizes (resp. varying number of UEs in the network); (ii) about 99% of reduction in terms of transmission energy dissipated by an UE during transmission of a file under varying data file sizes (resp. varying number of UEs in the network); (iii) improved performance with an increase in the number of small base stations in the network, (iv) significant reduction in the energy transmitted (by the UE) during transmission of big data files to the cloud storage; and (v) some stability irrespective of the variation in network conditions such as increasing the number of active UEs or increasing the number of UEs in the network.
