ABSTRACT
For supporting multimedia applications, it is desirable that an ad hoc network has a provision of quality of service (QoS). However, providing the QoS in a mobile ad hoc network is a challenging task. Quality of Service (QoS) means that the network should provide some kind of guarantee or assurance about the level or grade of service provided to an application. The definition for QoS and the QoS parameter may be considered different for different applications, which purely depends upon specific requirements of an application. For example, an application that is delay sensitive may require the QoS in terms of delay guarantees. Some applications may require that the packets should flow at certain minimum bandwidth. In that case, the bandwidth will be a QoS parameter. The other application may require a guarantee that the packets are delivered from a given source to a destination reliably; then, reliability will be a parameter for QoS.
