Using the IntelRate Controller to Improve Throughput and Queue Size of High-Speed WLANs
Jungang Liu, Oliver W. W. Yang · 2013
The IntelRate controller does not need to evaluate some critical network parameters (such as link bandwidth) as required in the existing explicit congestion controllers while performing better upon network parameter changes. In this paper, we will further experimentally investigate the IntelRate controller under dynamic bandwidth situations in WLANs (Wireless Local Networks) via OPNET simulation. Comparison with other recent controllers that need to estimate bandwidth shows that the IntelRate controller has greatly improved the adaptation capability and stability of the system. In the meanwhile, we also point out some response limitations under fast bandwidth variations that a designer should pay attention to.
