Mobile ad hoc networking does not possess any fixed infrastructure and hence, stable routing is the major problem. The mobility nature of MANET’s node facilitates rediscovery of a new path to organizing a routing. In order to intensify the Quality of Service and routing stability in MANET, we propose a Dynamic Quality of service Stability based Multicast Routing Protocol by modifying the Cuckoo Search Algorithm through a modernizing mechanism which is derived from the differential evolution algorithm. Tuned CSA is a combined feature of CSA and DE algorithms. Periodically, each node in the network creates neighbour stability and QoS database at every node by calculating the parameters like node and link stability factor, bandwidth availability, and delays. Finally, multicast path constructs route request and route reply packets, stability information and performing route maintenance.
