| Abstract: | The optimization of network performance should be improved considering the particularity of the UW-ASNs's channel.Under the circumstance of the random distribution of multi-nodes,this article studies and calculates the optimal length of data packet according to the different channel state,so as to achieve the goal of being adaptive.OPNET simulation is used to validate the analysis,and the simulation results show that the performance of network throughput would be improved as long as the length of frame is s... |
