The RED queue management algorithm achieves high throughput and low average delay by detecting and avoiding the incipient congestion. The detection of incipient congestion is based on calculation of average queue length and RED parameter settings. To avoid the congestion in the network, operators should have a priori estimations of average delay in congested routers, which is difficult to estimate in mobile ad hoc network due to uncertainty in changing the network conditions. To achieve high throughput and low delay, it needs constant tuning of parameters according to the current traffic condition. The authors' goal in this paper is to achieve high throughput and low delay in congested network by efficient parameter adjustment and continuous tuning of queue parameters according to the changing of network condition.
