碩士 === 國立交通大學 === 資訊工程系所 === 92 === With the rapid development of communication industry, there are many technologies developed to do wireless transmission. Because they all follow different standards, they have their own advantages and disadvantages. E.g. WLAN has higher transmission rate but shorter transmission distance, GPRS has longer transmission distance but lower transmission rate, in addition, you need to pay extra billing cost while you use GPRS to transmit data. In the thesis, we provide a TCP connection environment with better benefit by combining the advantages of WLAN and GPRS. When a user builds a TCP connection, this connection environment will dynamically choose a wireless technology according to the environmental condition of the user to guarantee the highest transmission rate and the lowest billing cost while transmitting data. This connection environment also needs to decrease the delay time while switching wireless technologies.
