This paper proposes an efficient automatic repeat request (ARQ) scheme to address the reliable broadcasting problem in wireless LANs. Based on a novel approach of virtual bitmaps, the proposed scheme achieves high efficiency in recovering broadcasting losses in wireless LANs but does not use out-of-band signals. The comprehensive simulation results in the paper show that, as compared with existing schemes, the proposed scheme improves node broadcast throughput by from several tens to more than one hundred percent in wireless LANs.
