| Abstract: | A gateway is utilized to realize the protocol conversion at application level.In order to provide reliable data transmission service on disturbed channels,a modified Go-Back-N ARQ protocol is used to retransmit data by a communication gateway.The communication gateway implementation method based on multithread technique is put forward,and some key techniques are discussed.The system's test results demonstrate that the communication gateway which makes use of the modified ARQ protocol and the technique discussed,can provide high reliability on disturbed channel and performs well in practice. |
