Optimization method through topology reconfiguration for mobile underwater wireless sensor networks
Published 2015-06-01“…The topology of mobile underwater wireless sensor networks (MUWSN) evolves dynamically with ocean currents,which will have great impact on network performance.To solve this problem,a topology optimization method for MUWSNs is proposed based on topology reconfiguration.Firstly,the proposed method optimizes the coverage rate of MUWSNs by adjusting the location of sensor nodes through simulating fish behaviors.Secondly,to optimize the connectivity of MUWSNs,the proposed method repairs disconnected positions and eliminates key nodes in MUWSN through using redundant nodes.Finally,simulation results verify the rationality and validity of the proposed method.Experimental results show that the algorithm can guarantee the network coverage is maintained at about 97%,connectivity rate above 89%,with lower energy consumption.…”

Radar marine maneuvering target detection via high resolution sparse fractional ambiguity function
Published 2019-08-01“…To solve the problem of fast detection of high maneuvering targets in complex ocean background,a radar target detection algorithm via sparse fractional ambiguity function (SFRAF) was proposed.The sparse Fourier transform (SFT) was introduced after instantaneous autocorrelation function calculation,which combines the advantages of SFT and fractional ambiguity function (FRAF).Therefore,SFRAF has good processing performance on high maneuvering signals and can achieve lower computational complexity.The simulation experiments and the measured data processing results show that compared with classical detection method,the detection performance of maneuvering target can be significantly improved,and compared with FRAF,the proposed method can achieve higher detection efficiency.…”
