چکیده On-Demand Multicast Routing Protocol (ODMRP) is a well-known protocol for ad hoc networks. This protocol is mesh based and exhibits a high packet delivery ratio even at high mobility. In ODMRP the robustness is achieved by using the number of multiple routes which is a solution for the high speed mobility and the subsequent route breaking. The ODMRP is such designed that the number of multiple routes only depends on the number of senders and receivers, irrespective of the node speed and the traffic load. In this paper we proposed a Reduced Data Transmission ODMRP (RDTODMRP) routing algorithm that considers the network conditions e.g. mobility speed and traffic load to determine the multiple routs. This cuts down the unnecessary redundant routes and their data transmissions. Furthermore in ODMRP and RDTODMRP, flooding of Join-Request packets causes excessive control overhead, In order to solve the problem, we Limit some nodes to Flood Join-Request packets and forbid it to be a forwarding node (LF-RDTODMRP). It is shown by simulation that the RDTODMRP and LF-RDTODMRP reduce the number of data transmission, control overhead, end to end delay and improve the data packet delivery ratio.
