Abstract

The invention discloses a hybrid MAC protocol optimization design method based on wireless optical communication, and the method comprises the steps: S1, enabling a Sink node to carry out the instruction wake-up of other nodes, enabling the other nodes to wake up at a random time, and starting to carry out the competition of a cluster head, and carrying out the preemption of a time slot; S2, entering a downlink transmission stage, performing relative positioning between nodes and cluster head updating tasks, and finishing downlink instruction transmission and cluster head updating tasks in each odd number of turns; and S3, entering an uplink stage, and performing time slot optimization in the delay tolerant network based on a time slot transfer mechanism of link quality evaluation. According to the time slot transfer mechanism based on link quality evaluation, time slot optimization in the delay tolerant network is carried out, and the time slot utilization rate of networking is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a hybrid MAC protocol optimization design method based on wireless optical communication. Background technique [0002] There are few existing methods for solving the delay-tolerant state in the optical communication network based on the MAC protocol. Some delay-tolerant MAC methods that focus on underwater acoustic communication networks are commonly used in two ways. One is to increase the time slot by retransmitting data. Utilization, but the essence of this method is to reduce energy consumption in exchange for an increase in time slot utilization, which is not a practical method for networks that are deployed underwater and difficult to replace and replenish energy; One is to balance the energy consumption of the network by adding AUVs to the network. This method is mainly used to reduce the delay tolerance caused by the unbalanced energy consumption of nod...
