In this paper, we present an intelligent on-demand multicast routing protocol (IOD-MRP) which is suited in rapidly changing network environments, such as ad hoc networks. This protocol simplifies and enhances the existing core-assisted mesh protocol (CAMP). The main difference between our protocol and CAMP is eliminating the cores from CAMP. We remove the cores from CAMP and apply an on-demand receiver-initiated procedure to dynamically build routes and maintain multicast group membership. In addition, flooding is an important issue in ad hoc networks and our protocol is able to reduce flooding messages. Simulation results show that IOD-MRP reduces number of control messages by 3% - 13% compared to CAMP, and still has slightly lower packet delay and packet loss rates.
