Since the structure is completely mobile, lack of central coordination, multi hop communications and limited resources provided by MANETs, QoS techniques need to be optimize the scare resource. A lot of research has been focused on providing QoS assurance in MANETs. The most important QoS metrics are packet delivery ratio, delay, through put and energy. It is a challenging issue to incorporate QoS to ad-hoc multicasting. In this paper, the QoS metrics of multicast routing protocols ODMRP, AM route and PUMA have been simulated using NS2 and analyzed.
