On-Demand Multicast in Mobile Wireless Networks
In this paper we propose an "on demand" multicast routing protocol for a wireless, mobile, multihop network. The proposed scheme has two key features: (a) it is based on the forwarding group concept (i.e., a subset of nodes is in charge of forwarding the multicast packets via scoped flooding) rather than on the conventional multicast tree scheme; (b) it dynamically refreshes the forward group members using a procedure akin to on demand routing (hence the name). "On Demand" multicast is well suited to operate in an On Demand routing environment where routes are selectively computed as needed between communicating node pairs instead of being maintained and updated globally by a routing "infrastructure" (like in Distance Vector or Link State, for example). On Demand Multicast is particularly attractive in mobile, rapidly changing networks, where the traffic overhead caused by routing updates and tree reconfigurations may become prohibitive beyond a critical ...
