    Delay is an unavoidable factor that occurs within networks and may be exacerbated by the nature of wireless ad-hoc networks. Maintaining a manageable
    level of delay may be required to provide satisfactory performance for each of
    the nodes that form the network. The variability of IoT devices, topologies
    and network conditions demand that a standalone and scalable scheme be used.
    ADTH is first shown to accomplish this through simulations with the NS-2 network simulator. The scheme was then used with testbed implementation with
    Gumstix devices and real-time traffic provided by an STC Traffic Generator.
    These demonstrated its effectiveness in managing flows of delay sensitive traffic,
    in addition to delivering superior bandwidth utilisation than standard policies.
