Multicast extensions to the Flow-Oriented Routing Protocol and Node Velocity-based Stable Path Routing Protocol for Mobile Ad hoc Networks

We propose multicast extensions to the flow oriented routing protocol (M-FORP) and node velocity based stable path (M-NVSP) routing protocol for mobile ad hoc networks. M-FORP predicts the link expiration time and connects the source to each of the multicast receivers through paths with the largest predicted expiration time. M-NVSP connects the source to each of the multicast receivers through paths with the smallest bottleneck velocity. The bottleneck velocity of a path is the maximum velocity of the intermediate nodes of the path. We compare the performance of M-FORP and M-NVSP with that of the bandwidth efficient multicast routing protocol (BEMRP). Simulation results illustrate a tradeoff between lifetime per multicast tree, average hop count per source receiver-path and the number of edges per tree. M-FORP yields the maximum lifetime per tree, M-NVSP yields lowest hop count per source-receiver path and BEMRP yields the minimum number of links per tree.
