Providing throughput guarantees in IEEE 802.11 wireless networks - An experimentally-driven study

Abstract

In this paper the experimental evaluation of the most critical operational QoS enabling parameters for IEEE 802.11e, with respect to service differentiation and throughput provisioning, over pragmatic conditions, is realized, exploiting the NETMODE wireless testbed. Capitalizing on the guidelines and observations that stem from this experimental study, a novel, asynchronous policy based resource allocation mechanism aiming at network's aggregate throughput maximization and stations' throughput prerequisites satisfaction for inelastic traffic is proposed. The operational effectiveness of the proposed method under pragmatic networking conditions is evaluated and tested for various scenarios implemented over the considered wireless testbed. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2013.
