On Demand Multicast Routing Protocol (ODMRP) is a multicast routing protocol
for mobile ad hoc networks. Its e±ciency, simplicity, and robustness to mobility
render it one of the most widely used MANET multicast protocols. At the heart
of the ODMRP's robustness is the periodic route refreshing. ODMRP rebuilds the
data forwarding \mesh" on a ¯xed interval and thus the route refresh interval is a
key parameter that has critical impact on the network performance. If the route re-
fresh rate is too high, the network will undergo too much routing overhead wasting
valuable resources. If it is too low, ODMRP cannot keep up with network dynam-
ics resulting in packet losses due to route breakages. In this paper, we present an
enhancement of ODMRP with the refresh rate dynamically adapted to the environ-
ment. Simulation results show that the Enhanced ODMRP (E-ODMRP) reduces
the packet overhead by up to a half yet keeping a packet delivery ratio compara-
ble that of original ODMRP. E-ODMRP compares favorably with other published
multicast schemes.
