Abstract: This paper proposes a multicast protocol utilizing ondemand routing strategy for mobile packet radio network. It does not maintain permanent route tables with full topological views. Instead, multicast senders apply on-demand procedures to dynamically discover routes and build forwarding group in this protocol. The data packets are propagated by each forwarding ,group member via scoped floodingso the protocol can reduce network bandwidth overhead and avoid the propagation of potentially large routing updates throughout the network.
