摘要

Since IEEE 802.11ad doesn't have any recovery mechanism for multicast technology at Media Access Control (MAC) layer, the lost packets can't be detected and retransmitted under the influence of interference, conflictions or other issues. Given this, a Multi-Leader Based Protocol (MLBP) is proposed to reduce the control overhead under the premise of improving the reliability of Millimetre Wave WPANs (Wireless personal area networks). Meanwhile, a leader polling mechanism is raised so that each receiving node could communicate with the multicast source directly and equally. Theoretical analysis and simulation results show that MLBP is not only simple and feasible but also has great advantages in time delay and throughput.
