Latency Reduction for Mobile Edge Computing in HetNets by Uplink and Downlink Decoupled Access

Achieving an end-to-end low-latency for computations offloading, in Mobile Edge Computing (MEC) systems, is still a critical design problem. This because the offloading of computational tasks via MEC servers entails use uplink (UL) and downlink (DL) radio links that are usually assumed to be coupled single base station (BS). However, heterogeneous networks, new architectural paradigm whereby UL DL not associated with same BS proposed seen provide gains network throughput due improved performance. Motivated by such gains, using typical results from stochastic geometry, we formulate latency MEC-based scheme decoupled UL/DL association, or access, compare its performance conventional access scheme. Despite backhaul delay necessary communication between two serving BSs DL, capable providing fairly lower compared access.
