| Abstract(in English) | With the proliferation of new wireless service, a scarcity of wireless resources will arise and become a critical issue. For this reason, cognitive radio mobile ad hoc networks (CogMANET)are being developed as a promising solution to this problem. However, in CogMANET, channel switching is inherently necessary whenever a primary user with a license appears on the channel. Allowing secondary users to choose an available channel from among a wide range of the spectrum thus enables reliable communication in this context. In such cases, the communication characteristics also change in terms of bottleneck bandwidth and RTT. In response to this change, TCP has to adaptively update its congestion window size (cwnd)to make an efficient use of the available wireless resources. For this purpose, TCP CRAHN was proposed for CogMANET. TCP CRAHN dynamically changes its cwnd, but it can excessively increase its cwnd compared with available buffer space of relay node when the band- width increases drastically. Hence, we propose the new TCP, TCP CoBA, which updates the cwnd based upon the available buffer space in the relay node as well as the bandwidth-delay product (BDP).Through simulations, it is shown that compared with TCP CRAHN, TCP CoBA improves the throughput performance by up to 200‰ |
