The paper presents a video multicasting architecture for Mobile Ad-Hoc NETworks (MANETs). The proposed framework uses the Scalable, Noncausal Predictive codec with Vector Quantization and conditional Replenishment (SNP/VQR) for encoding video into multiple layers of data streams at bit rates between 10Kbps to 500Kbps. A Rate Adaptive Multicast (RAM) routing algorithm is proposed, which dynamically adjusts the transmission rate based on the channel quality to obtain the optimum throughput. The scalability of SNP/VQR, coupled with RAM, enables strong resilience against bandwidth fluctuations as well as the capability to support a range of heterogeneous mobile receivers.
