Embodiment Construction
[0055] The following embodiments will describe the present invention in detail with reference to the accompanying drawings.
[0056] Based on the underwater acoustic communication energy consumption model and combined with cooperative communication technology, the present invention can quickly find the path with the least energy consumption in the underwater acoustic multi-hop cooperative communication network, including the following steps:
[0057] 1) Select the source node S, the destination node D, and set the relay node and the cooperative node to have a total of Nodenumber; number the candidate routing nodes and calculate the distance between any two nodes, node i and node j; set d i,j Indicates the communication distance between any two adjacent nodes; r 1 Indicates whether the lower limit of the distance threshold between node i and node j requires the participation of cooperative node C, that is, d i,j less than r 1 When node j can successfully decode the informatio...
