摘要
To safely transfer a broadcast packet to all nodes in computer networks is an important issue. However, it is a big challenge to transfer broadcast packets over wireless networks reliably due to the unsettled wireless links and lack of the acknowledgment (ACK) scheme. Therefore, in this paper, we proposed a reliable broadcast scheme named broadcast engagement ACK mechanism (BEAM), which is completely compatible with the IEEE 802.11 protocol, in the data link layer rather than the network layer. This is because that the overhead of raising the reliability of broadcast transmission in network layer would be significantly reduced in data link layer. Simulation results show that the proposed BEAM can reach approximate 100% reliability even in heavy traffic load. Besides, by using the proposed mechanism, the IEEE 802.11 protocol could provide the reliability of unicast transmissions as well as broadcast transmissions and avoid redundant control overhead.
