Opportunistic routing is a recent routing paradigm that achieves high throughput in the face of universally lossy wireless links in mobile ad hoc networks, likewise, network coding popularly investigated by many institutes is another approach for improving the throughput in wireless networks. How to combine both the techniques is an interesting research. To our knowledge, this is still an open issue to implement the multicast routing in mobile ad hoc networks simultaneously employing both the mechanisms. Due to feedback explosion, most existing wireless network multicast protocols do not guarantee the reliable delivery. In this paper, we propose a novel reliable multicast protocol based on the opportunistic routing and network coding. Additionally, we also provide an expected number of transmission-based cost metric formula of the multicast sub-group. Extensive simulation reveals that the performance of the novel presented multicast routing protocol outperforms the conventional multicast routing protocol in ad hoc wireless networks.
