Abstract(in English) | With the development of satellite network technology, satellite networks have become widely utilized for many communication applications, thus, the reliability of the Transmission Control Protocol (TCP) has become ever more essential. However, it is commonly known that the performance of TCP will significantly decreases in wireless networks that have long transmission delay, such as satellite networks. Even though some improvements in TCP have already addressed these problems in previous works, we focus on the Variable-structure congestion Control Protocol (VCP) which is designed for High Bandwidth Delay Product (BDP) networks. VCP allows the sender to control the congestion window efficiently by using Explicit Congestion Notification (ECN) which conveys congestion information that originates from the routers. However, the performance of VCP degrades in wireless networks because of the inefficient retransmission control. In this paper, we propose two methods that improve retransmission control. The first method is based on the use of ECN ,while the other utilizes Round Trip Time (RTT), to estimate network condition. Finally, we also evaluate the effectiveness of the proposed schemes by the use of computer simulation. |
