In IEEE 802.11 Wireless LANs current standard MAC layer protocols do not provide any error correction scheme for broadcast/multicast. In the authors' previous work, they enhanced a Leader Based Protocol (LBP) and proposed a Beacon-driven Leader Based Protocol (BLBP) for the MAC layer multicast error control. In this paper, they combine BLBP and packet level Forward Error Correction (FEC) and propose a Hybrid Leader Based Protocol (HLBP). HLBP transmits the original data packets using raw broadcast and retransmits parity packets using an improved BLBP which is based on block feedback.
