Wireless Mesh Networks (WMNs) is becoming an emerging paradigm, due to its simple and cost effective deployment, and increased growth in popularity for the next generation wireless Internet. Unlike the single channel, it is challenging to provision a robust multicasting by means of multi-channel and multi-interface WMNs. Therefore, in order to tackle the multicast issues, a high-quality path selection and channel assignment are essential. The proposed Quality of Service – On Demand Multichannel Multicast Routing Protocol (QoS- ODMMRP) includes merged path selection and top-down channel tuning mechanism to support multi-channel and multi-interface WMNs. Thus, the proposed work reduces the number of transmissions and increases the communication throughput efficiently.
