| The thesis is based on the project –Information Network Demonstration System of the Ocean,aiming at the problem of the deployment optimization in marine integratedinformation equipment.The model of the marine integrated-information equipment,the mathematical model of the deployment optimization problem in marine integratedinformation equipment and an algorithm to solve it is presented first.The model of the marine integrated-information equipment is defined through detection & perception part,communication part and energy part.The detection& perception part consists of radar detection,photoelectric detection,target recognition and electromagnetic situation awareness.The communication part contains short wave communication,ultrashort wave communication,scatter communication and satellite communication.The problem of the deployment optimization in marine integrated-information equipment,a multi-objective and multi constraint problem,is analyzed to get the basic requirement of it.The mathematical model of the problem is divided into three parts: the static covering capacity,the dynamic detection ability and the ability of communication,including the bool covering model,the model of detection probability with various distance and Longley-Rice model,offering optimal objectives and constraints.And then the algorithm to solve the optimal deployment problem,which is aiming at the objectives of maximizing the abilities of static coverage,dynamic detection of equipment network and the abilities of communication,based on the differential evolution algorithm,is presented,including key operations and detailed steps.The algorithm is also designed to ensure communication connectivity of the equipment network.At the last of the thesis,Through comparing the simulation result of optimal deployment with that of random deployment,it is found that the optimal deployment,which is based on differential evolution algorithm,has a faster convergence rate and is effective in improving the static coverage and dynamic detection of equipment network.The algorithm has been applied in the Information Network Demonstration System of the Ocean project. |
