A Revisit to MRPs (Multicast Routing Protocols)

In general, there are three types of routing mechanism in MANET. Proactive (table driven) protocols use a traditional, distributed, shortest-path and maintain routes at all times. They impose a high overhead. Reactive (on-demand) protocols are initiated by the source. They have lower traffc compared with proactive protocols, but impose delay in route determination. Hybrid protocols are an adaptive way of combining proactive and reactive protocols.

DVMRP (Distance Vector Multicasting Routing Protocol) builds a source-based tree. AODV (Ad-hoc On-Demand Distance Vector Routing Protocol) builds a corebased tree. CAMP (Core Assisted Mesh Protocol) builds a mesh interconnection of hosts.
