握手是用于避免陆地和水下基于内容的网络中的冲突的常用技术。然而，由于水声信道的长传播延迟，传统的握手机制，它只允许一个成功的握手和一对节点进行通信的每个传输周期，在水声网络中变得不太有效。提出了一种新的分布式水声网络调度方法，该方法支持单跳簇在一个传输周期内的多次握手和并发传输。提出了一种确定性调度算法，对源节点的发送顺序和发送时间进行联合优化，在避免多个并发传输冲突的同时缩短了数据传输总时间。确定性调度算法还可以减少调度开销，并通过标准双向握手以分布式方式实现数据并发传输的同步。仿真结果表明，该方法在归一化吞吐量、分组投递率、平均端到端时延和平均能耗等方面均优于传统的水下媒体接入控制协议.
Handshaking is a common technique used to avoid collisions in terrestrial and underwater content-based networks. However, due to the long propagation delay of the underwater acoustic channel, the conventional handshaking mechanism, which only allows one successful handshake and one pair of nodes to communicate per transmission cycle, becomes less effective in underwater acoustic networks. This paper proposes a new distributed scheduling method for underwater acoustic networks that supports multiple handshakes and concurrent transmissions in one transmission cycle for one-hop clusters. A deterministic scheduling algorithm was developed to optimize the sending sequence and time of the source nodes jointly so that the total data transmission time is shortened while avoiding collisions among multiple concurrent transmissions. The deterministic scheduling algorithm can also reduce the scheduling overhead and enables the synchronization of the data concurrent transmissions in a distributed manner via the standard two-way handshaking. Simulation results show that the proposed method outperforms several conventional underwater medium access control protocols in normalized throughput, packet delivery rate, average end-to-end delay, and average energy consumption.
