A review and performance comparison of QoS multicast routing protocols for MANETs

Nowadays supporting real-time and multimedia applications have become more essential for the users of mobile ad-hoc networks. QoS multicast routing protocols provide a mechanism to establish a multicast session. Considering the fact that a number of different parameters affect on the quality of service, each of the existing protocols has dealt with a particular type of those parameters. In this paper, an overview of QoS multicast protocols which have been proposed in the past literatures are presented. In addition, the performances of these protocols are compared with respect to performance metrics.
