In MANETs, real-time multimedia applications make Quality of Service (QoS) support, a crucial issue regarding terms of increased throughput, reduced jitter and available bandwidth. The highly dynamic topology of the network, large variation of received signal strength at nodes and frequently varying link characteristics make QoS provisioning, a challenging task. Most of the existing routing protocols focus on straight forward hop-count metric and are less adaptable to densely distributed and highly mobile networks. Therefore, Multicast communication with QoS in densely populated highly dynamic network an interesting research challenges. The objective of the present paper is to introduce a QoS aware routing metric that determines a reliable forwarding node based on Link Stability cost Function (LSF). The principle theme underlying our protocol is optimum contention count that can be estimated with the help of received signal strength. Our proposed protocol has been demonstrated on an existing mesh-based Multicast routing protocols, ODMRP. Simulations are carried out on Exata/Cyber simulator, and obtained results are compared with that of ODMRP. The comparative analysis reveals that our protocol is more efficient in contrast to ODMRP, LSMRP and MMRNS, regarding performance parameters like PDR, latency and route lifetime.
