A multicast routing protocol manages group membership and controls the path that multicast data takes over the network in mobile ad hoc network. This process is done through either tree-based or mesh-based protocols. The mesh-based protocols are more reliable and robust against the tree based protocols. One of the most used on-demand multicast routing protocol is ODMRP (On-Demand Routing Protocol). However, it has the significant overhead due to redundant data delivery group and path maintenance. This overhead has been eliminated through the forwarding node reduction and link break time prediction algorithm (FNRLP). This work aims to exhibit the performance characteristics of mesh-based on-demand multicast routing protocols ODMRP and ODMRP-FNRLP
