Quality of Service (QoS) support in Mobile Ad-hoc NETworks (MANETs) is a challenging task. The major challenge in ad hoc networks lies in adapting multicast communication to environments, where mobility is unlimited and failures are frequent. Such problems increase the delays and decrease the throughput. To meet these challenges, to provide QoS, and hence to improve the performance, Bandwidth Control Management BWCM model can be used. In this paper, to provide the BWCM model that decrease MAC delay for real and non-real time application in wireless ad hoc network. In order to enhance the control of congestion, a BWCM model has been proposed for bandwidth management in mobile ad hoc networks that has a significant influence on the performance on network in term of delay. The proposed model achieves a reduction in terms of average delay by about 60-70% in comparison to the original model at a cost of about 15% decrease in throughput. The average delay obtained is quite stable and low under different channel conditions, mobility scenarios, and traffic scalability. The performance of this model is studied using NS2 simulator under different load and speed condition and DSDV as a routing protocol has been used. The proposed model to be an efficient tool for reducing the delay of real and non-real time application in MANET.
