Design And Implementation Of Fishing Terminal Software Based On Ad Hoc Intelligent Router

There are a vast sea area,rich marine resources,many ports and a large number of marine fishery staff in China,and the marine fishery plays an important role in chinese economic development.With the development of communication technology and Internet,it is urgent to research more advanced marine fishery communication system.Ad hoc network is characterized by decentralized,self-organizing and fast construction without relying on fixed infrastructure.Therefore,it is suitable for marine communication system without fixed base station and with dynamic network topology change.The fishery terminal based on ad hoc intelligent router can construct the marine fishery ad hoc network and realize the function of communication between ships.This thesis designs an application software of fishery terminal based on ad hoc intelligent router,and proposes a resource scheduling mechanism of fishery ad hoc network with reinforcement learning.The main research contents and achievements are as follows:1.By using Android operating system,we realize the human-computer interaction software of fishery terminal based on ad hoc intelligent router.Compared with the small embedded operating system used by traditional fishery terminal,the human-computer interaction experience is improved.The main interface of human-computer interaction is realized by four parts: video playback,the rolling display of real-time broadcast message,real-time ship information display and other prompts;The human-computer interactive input is realized by using the USB keyboard and the intelligent input method.The test results show that the designed terminal human-computer interaction function meets the communication requirements and has a good interaction experience.2.In order to meet the needs of users using fishery terminal to watch radio programs,a streaming media player software for fishery terminal based on ad hoc intelligent router is designed and developed.The broadcast program is transmitted by the audio and video broadcast server of the fishery communication system.After being transmitted by wireless,it is received by the ad hoc intelligent router,and then the router sent it to multiple terminals with Android operating system through Wi Fi.The developed player software uses the FFmpeg tool to decode,unpack and process the received streaming media data,so as to get the original audio and video data,and then call the related application program interface to play the audio and video.The test results show that the player software works well.3.A resource scheduling mechanism of ad hoc network for fishing based on intensive learning is proposed.The mechanism takes the priority of different communication services into account.According to the status of communication service data flow and fishery ad hoc network,the occupied network bandwidth resources are dynamically allocated for different communication service data streams,and the performance of ad hoc network for fishing is improved.The simulation results show that the proposed resource scheduling mechanism has higher user satisfaction than that of(First Come First Served)FCFS mechanisms and(Roll Polling)RP mechanisms.
