THE COMMUNICATION PROTOCOL IN MOBILE FIELD INFORMATION INTELLIGENT SERVICE SYSTEM BASED ON GPRS

摘要

Mobile Field Information Intelligent Service System transfers the field information, which is collected by the wireless sensor network based on ZigBee technology in real-time, to the remote server by the mobile terminals (PDA) through GPRS. It manages the field information and makes the field decision by the Field Information Service System which is installed in the remote server. The long-range wireless network communication protocol is very important to ensure the validity of field information in the Mobile Field Information Intelligent Service System. The long-range wireless network communication protocol is responsible for the information exchanging and synchronization between the host server and the PDA. According to the work characteristics of Mobile Field Information Intelligent Service System and the content of network transmission, this paper presents a wireless network transmission protocol based on TCP/IP which makes the rules of information transmission between Host Information Service System and PDA. With the protocol, Mobile Field Information Intelligent Service System realizes the seamless connection between remote server and mobile terminals, and the remote host server can manage mobile terminals effectively.
