    The Advantage of Computation Offloading in Multi-Access Edge Computing


    Singh, R, Armour, S, Khan, A, Sooriyabandara, M & Oikonomou, G, 2019, ‘The Advantage of Computation Offloading in Multi-Access Edge Computing’.


    Computation offloading plays a critical role in
    reducing task completion time for mobile devices. The advantages
    of computation offloading to cloud resources in Mobile Cloud
    Computing have been widely considered. In this paper, we have
    investigated different scenarios for offloading to less distant
    Multi-Access Edge Computing (MEC) servers for multiple users
    with a range of mobile devices and computational tasks. We
    present detailed simulation data for how offloading can be
    beneficial in a MEC network with varying quantitative mobile
    user demand, heterogeneity in mobile device on-board and MEC
    processor speeds, computational task complexity, communication
    speeds, link access delays and mobile device user numbers.
    Unlike previous work where simulations considered only limited
    communication speeds for offloading, we have extended the range
    of link speeds and included two types of communication delay.
    We find that more computationally complex applications are
    offloaded preferentially (especially with the higher server:mobile
    device processor speed ratios) while low link speeds and any
    delays caused by network delays or excessive user numbers
    degrade any advantages in reduced task completion times offered
    by offloading. Additionally, significant savings in energy usage by
    mobile devices are guaranteed except at very low link speeds.
