Due to its bandwidth efficiency, multicast makes a group-centric communication more viable in wireless ad hoc networks with limited radio resources. PIM-SM, a de facto standard multicast protocol known for its high scalability, is a good fit for a large-scale ad hoc network. However, it does not provide a robust multicast communication under RP outage and host mobility. In this paper, we propose a robust way of configuring PIM-SM using Anycast RP in wireless ad hoc networks. We analyze the impact of cardinality and locations of anycast RPs on the network performance under node mobility. Based on these observations, we find metrics for near-optimal cardinality of anycast RPs and propose a novel RP selection scheme. The proposed scheme is proven to make PIM-SM robust against mobility while satisfying QoS requirements and maintaining the scalability of PIM-SM.
