水声通讯网的媒质访问控制协议(MAC)要求避免各个节点使用信道时产生冲突,减少同信道干扰,且要尽量提高信道利用率,减少平均时延,增加吞吐量。提出了一种基于轮询的负载可感知的轮询协议,描述了该协议的工作流程,并对协议进行了仿真。该协议在避免冲突的同时能够根据网络中每个节点的负载情况为它们分配不同的信道占有时间,从而改善了信道利用状况,适合用于集中式小型水雷网络。
The media access control protocol (MAC) of the underwater acoustic communication network requires avoiding collision when using the channels at each node, reducing co-channel interference, maximizing channel utilization, reducing average delay and increasing throughput. A load-aware polling protocol based on polling is proposed. The workflow of the protocol is described and the protocol is simulated. The protocol can avoid the conflict and allocate different channel occupancy time to each node according to the load of each node in the network, thus improving the channel utilization and being suitable for the centralized small-scale mine network.
