Design And Implementation Of Collaborative Control Communication System

For current travel or group activities,in order to solve the problem of coordination and communication between group leaders and group members in group activities,and strengthen the communication between leaders and members in group activities,based on Wi-Fi Direct P2 P direct-connect technology,combined with the current popular Android system,this paper has designed a collaborative system for random dynamic set-up,voice broadcasting,short-distance roll call,message distribution,and location sharing.This paper studied the advantages and disadvantages of the existing broadcast protocol in wireless network,this paper proposes a more chance to confirm broadcasting mechanism,through simulation verification show that many opportunities to confirm broadcast mechanism to improve the reliability of the broadcast messages.Then,a collaborative command system based on Wi-Fi Direct technology was designed,which was composed of group owner,group client,server and Web background management.Group owner and group clients are randomly set up to create a one-to-many mobile group network via Wi-Fi Direct close range Direct connection technology.In a group network,the group owner can broadcast voice messages to the group network and send reliable broadcast messages to the group network through a multi-opportunity confirmation broadcast mechanism.With the help of the location service provided by Baidu Map,the group owner can broadcast its location information to the clients of the group network through Wi-Fi P2 P direct connection and mobile network communication.The group clients can also report their own location information to the group owner in the same way and mark it on the map with realizing the sharing of location information.The Web backstage management side implements the function of issuing message announcements to the whole network.Finally,the functional integrity and stability of the network system are tested on the hardware platform of Android system.After testing and verification,the system has the advantages of simple hardware requirements,dynamic networking,voice broadcast,reliable release of news,location sharing,close range count,etc.This system can be conveniently applied to the management of travel group activities,natural disaster relief,and has certain application value.
