Optimization of Energy Consumption and Covert Communication for Multi-hop Underwater Acoustic Cooperative Networks
摘要
Abstract
Multi-hop underwater acoustic (UWA)cooperative network can not only improve the data transmission rate but also re-duce the energy consumption of the system.Yet its covertness of communication is greatly reduced.The aim of this paper is to study how to select the optimal number of hops in the same probability of detection (P D )to minimize the energy consumption of the sys-tem for the multi-hop UWA cooperative network.First,the paper presents the P D model of the UWA cooperative network under cer-tain distance to obtain the relationship between P D and the number of hops.Then,the energy consumption calculation model of the system is established to analyze the energy consumption and the number of hops for the system.Finally,considering both P D and en-ergy consumption,we simulate and analyze the influences of some factors,such as signal-to-noise ratio and communication distance. Simulation results show that the number of hops can be set between 2 and 6,which can meet the covert communication requirement with the P D less than 0.5 ,and the system energy consumption is relatively low.关键词
