Abstract: A communication design of multilevel structure for a remote wireless monitoring system is given out, which is based on the secondary C/S model, according to the comparison of data communication between B/S and C/S. The Socket based on TCP/IP protocol is applied to achieve the individual network communication between server and multiple clients. And then the design and implementation of system's whole network structure, the server, and the client are realized. In order to guarantee the system's data security, further analysis and research are made from different aspects of identity authentication, access control and user right management.
