摘　　要：提出了一种单信道无线多跳网络同步媒体接入控制协议three-handshake broadcast protocol(THBP).采用基于收节点冲突发现机制的三握手过程,解决无线多跳网络中难以保证广播业务传输可靠性的问题.通过控制分组三次交互,可为节点调度可靠广播信道.广播信道调度过程中,信道冲突由收节点探测并报告.分析结果表明,该协议能利用较小的开销,保证广播分组的可靠发送.The three-handshake broadcast protocol （THBP） was introduced as a single channel synchronous media access control protocol for multi-hop wireless networks. In THBP, a receiver-based conflict detection mechanism as well as a three-handshake process of the control packets was designed to ensure the reliable transmission of broadcast services. By three handshakes of the control packets, it allows nodes to schedule a conflict-free broadcast channel. Within scheduling process, the collisions were detected and reported by the destination nodes. The study shows that the protocol can ensure higher transmission reliability of the broadcast packets with the lower overhead.
