Multicasting is influenced with increasing importance of real-time and multimedia with different quality of service (QoS) requirement. But mobile ad hoc network (MANET) has limited bandwidth and also the physical channel results in unpredictable resource fluctuation and interference. In order to overcome these issues, resource allocation and rate adaption technique for multicast of real-time traffic in MANET is proposed. In this technique, reservation protocol is used while transmitting real-time data packets in order to reserve future slots and hence, it can be deployed in particular time slot. A three hop slot assignment mechanism is adopted to provide an interference free model. Also, normalised transmission rate is used to characterise transmission rate adoption. The benefit of using this technique is that even if a single copy of data is transmitted by sender, multicast receiver can hear the transmitted signal for each multimedia layer.
