On-Demand Multicast Routing Protocol (ODMRP) is well suited for ad hoc wireless networks with mobile hosts where bandwidth is limited, topology changes frequently, and power is constrained.Abstract:
An ad hoc network is a dynamically reconfigurable wireless network with no fixed infrastructure or central administration. Each host is mobile and must act as a router. Routing and multicasting protocols in ad hoc networks are faced with the challenge of delivering data to destinations through multihop routes in the presence of node movements and topology changes. This paper presents the On-Demand Multicast Routing Protocol (ODMRP) for wireless mobile and hoc networks. ODMRP is a mesh-based, rather than a conventional tree-based, multicast scheme and uses a forwarding group concept; only a subset of nodes forwards the multicast packets via scoped flooding. It applies on-demand procedures to dynamically build routes and maintain multicast group membership. ODMRP is well suited for ad hoc wireless networks with mobile hosts where bandwidth is limited, topology changes frequently, and power is constrained. We evaluate ODMRP performance with other multicast protocols proposed for ad hoc networks via extensive and detailed simulation.read more

Codecast: a network-coding-based ad hoc multicast protocol
TL;DR: Simulation results show that in a typical setting, CodeCast yields a nearly 100% delivery ratio, as compared to a 94 percent delivery ratio by traditional multicast, and the overhead is reduced by as much as 50 percent.

Opportunistic flooding in low-duty-cycle wireless sensor networks with unreliable links
TL;DR: Opportunistic Flooding is introduced, a novel design tailored for low-duty-cycle networks with unreliable wireless links and predetermined working schedules and achieves significantly shorter flooding delay while consuming only 20-60% of the transmission energy.

Flooding for reliable multicast in multi-hop ad hoc networks
TL;DR: It is demonstrated that even flooding is insufficient for reliable multicast in ad hoc networks when mobility is very high, and traditional multicast approaches are not appropriate.
