ADTH: Bounded nodal delay for better performance in wireless Ad-hoc networks

摘要

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. (C) 2018 Elsevier B.V.
