Abstract-We present the protocol for unified multicasting through announcements (PUMA) in ad-hoc networks, which establishes and maintains a shared mesh for each multicast gmup, without requiring a unicast routing protocol or the preassignment of cores to groups. PUMA achieves a high data delivery ratio with very limited control overhead, which is almost constant for a wide range of network conditions. Using simulations in Qualnet 3.5, we compare PUMA with ODMKY and MAODV, which are representatives of mesh-based and tree-based multicast routing in ad hoc networks. The results from a wide range of scenarios of varying mobility, group members, number of senders, t r s c load, and number of multicast groups show that PUMA attains higher packet delivery ratios than ODMRP and MAODV, while incumng far less control overhead.
