The routing efficiency in Mobile Ad Hoc NETworks (MANETs) suffers from frequent battery drains, mobility and large variation of received signal strength. Thus, nodes and links in MANETs become more vulnerable and unstable. Multicast routing in MANETs for group communication requires establishment of reliable links between neighbouring nodes called as reliability pair beginning from the source and extending such reliability pairs enroute to the destination. If there are multiple paths from source to every multicast destination, the reliability of source information may be enhanced by sending higher priority information on higher priority path.
