摘　　要：全网广播是一种非常重要的通信模式,可广泛应用于全网通告、寻呼、路由发现等。在军用无线自组网中,可靠传输非常重要,全网广播需要确保所有节点都能正确收到广播消息。然而,由于高速移动、强烈干扰等原因,实际的无线链路非常不可靠,有时需要多次重传,降低了传输效率。如何高效地实现全网可靠广播是军用无线自组网中需要亟待解决的问题。本文提出了一种高效的全网可靠广播协议,该协议采用基于链路感知的连通支配集选择算法,产生更高效的广播虚拟骨干网。Network-wide broadcast is a very important pattern, and can be applied in network-wide notification, paging, routing discovery, and etc. In military wireless ad hoc networks, reliable transmission is very important and network-wide broadcast must ensure al nodes can receive the broadcasting message. However, due to high mobility and strong interference, the factual wireless links are not reliable, multiple retransmissions are sometimes needed and that decreases the efficiency. How to implement network-wide reliable efficiently is a key problem for military wireless ad hoc networks. This paper proposes a link-aware network-wide broadcast protocol （LANWB）, which uses a link-aware connected dominating set election algorithm to generate the more efficient broadcast backbone.
