In Mobile Ad-hoc NETworks (MANETs), Quality of Service (QoS) of a multicast protocol is one of the most important performance metrics. Channel conditions and network topology frequently change, and in order to achieve a certain QoS, complex algorithms and protocols are needed. Often channel conditions are neglected during the design of a multicast protocol. However, vulnerability against channel errors can severely cripple the performance of a multicast protocol. Mesh networking inspired multicasting approaches introduces increased redundancy in the routing process to overcome the performance loss due to channel errors. Although utilizing multiple paths from senders to receiver's results in higher reliability, under better channel conditions the additional redundancy may not be needed in terms of reliability, and increased redundancy causes increased overhead.
