Embodiment Construction
[0028] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.
[0029] see Figure 1 to Figure 3 , an underwater acoustic media access control method based on a reservation scheduling mechanism, which includes several fixed nodes A, B, C, D and a unique mobile Sink node, and communicates in the following manner:
[0030] S1. The mobile Sink node broadcasts and sends an ND packet to the outside, and the ND packet includes a destination address, a source address, and a sending time;
[0031] S2. The fixed node that receives the ND packet, if there is a demand for data transmission, selects a random delay time, and sends an RTS packet to the mobile Sink node to make a data transmission reservation after the delay time is exhausted. The RTS packet contains the destination address and source Information such as address and de...
