Research On Personal Location Sharing System Based On Wireless Ad Hoc Network

At present,the technology of wireless ad hoc network is widely applied in all as-pects of social life.Personal location sharing has wide application demand in disaster search and rescue,team work,environmental monitoring and other fields.Based on this,the thesis focuses on the personal location sharing system based on wireless ad hoc network technology.Based on the theory of wireless ad hoc network and location sharing,a personal location sharing network model based on wireless ad hoc network is designed.Based on this,the functional requirements of system business are designed and analyzed,and the overall architecture of hardware and software is designed.Then,on the basis of the overall design,the system is divided into different modules for hardware design and software design and development with modular design method.In the hardware aspect of system,a handheld personal location sharing device based on ad hoc network is designed by using Altium Designer.The device consists of WIFI communication module,GNSS position sensing module,ARM main control module,wireless transceiver module and serial communication module and power module.These modules constitute a system of self-network location sharing hardware system.Software system is based on C language on Keil for ARM integrated development environment,five modules are mainly designed:basic driving module,time slot man-agement module,time synchronization module,information display module and launch management module.The wireless self-organizing network management algo-rithm is embedded,and the multi terminal self-organized personal location sharing communication system is realized.Finally,the practical application system is built and tested.The results show that the system can operate normally and stably and the location of multiple terminals can be shared.
