In order to reduce the risk of operation,the unmanned ship technology has been gradually applied in the field of marine environmental survey,marine environmental protection,maritime emergency search and rescue,maritime military field.In the future,with the continuous development of unmanned ship technology and the continuous decline in manufacturing costs,unmanned vessels will become the mainstream technology of marine economic operations and military applications.Therefore,the research on multi unmanned aerial vehicle cooperative communication technology will provide technical preparation for the unmanned ship cluster application.The application of cluster technology in unmanned aerial vehicle cluster based on the existing communication technology and equipment.With the continuous improvement of the performance of the directional antenna,the shape is more compact and more flexible in practical applications.In the unmanned ship group sea situation,in the process of loading the directional antenna multi unmanned ship operations,according to the different environment,especially the big waves in the sea,the research of wireless self-organizing network topological structure formed by the special environment of fast change of wind direction is also more and more.In this paper,the topology control algorithm of wireless network based on directional antenna is studied.In the traditional topology control algorithm,equipped with directional antenna in wireless ad hoc networks need more excellent characteristics such as standard,which involves how to quickly build the topology of the network is realized under the condition of minimum energy consumption structure.Since the traditional network topology control algorithm,is generally distributed topology algorithm to solve fault rate,or topology algorithm based on node location,the above algorithms lead to the connectivity of unmanned ships in maritime operations are relatively poor.For this reason,this paper proposes an improved topology control algorithm based on directional antenna.This algorithm takes into account the energy consumption problem of unmanned ship formation in order to form a connected network with minimum power consumption.The experimental results show that the algorithm can effectively solve the problem of the formation of the unmanned aerial vehicle in the dynamic situation and reduce the energy consumption.In addition,this paper also studies the topology algorithm of multi unmanned ship ad hoc network based on multi task,which can meet the requirements of different tasks.
