The lack of fundamental understanding of real achievable multicast delay performance in mobile ad hoc networks (MANETs) severely hampers the broad potential applications of such networks. The paper studies the real achievable multicast delay performance in MANETs under a general two hop relay routing with packet replication (THR-(f, g) for short), where f represents the number of replicated packets, and grepresents the number of destination nodes each source node is associated with. Under the THR-(f, g) routing, each packet at source node is delivered to at most f distinct relay nodes, and each of the g destination nodes will receive the packet from either one of the relay nodes or the source node. To study the multicast delay performance, we develop a Markov chain based theoretical model to characterize the packet delivery process under the THR-(f, g) routing, based on which the analytical expression on mean value of multicast delay is further derived. Extensive simulations and numerical results are presented to validate the accuracy of the theoretical model in multicast delay analysis and to explore the impact of network parameters on the multicast delay performance of the THR-(f, g) routing, respectively.
