An adaptive window increment based BIC TCP algorithm for improved data transfer in satellite network

In the previous work [7], it was realized that the performance of bic-tcp was good under satellite network. In this work, the perforce bic-tcp is improved and art adaptive window increment based bic-tcp algorithm (bic_AWI) for improved data transfer in satellite network is proposed. Further, the handovers in a satellite tcp connection may cause a break in communication for a fraction of a second and will affect a voice communication. Even though, such occasional breaks will not affect the non real-time data traffic considerably, in our version of the improved bic-tcp, we considered the satellite terminal handoffs also. We, implemented the idea on ns2's implementation of bic tcp. Proposed modifications has been made on bic-tcp, and the performance of the improved protocol “bic_AWI” has been compared with normal bic-tcp under Iridium satellite constellation. The performance of the algorithms has been measured using suitable metrics and the proposed bic_AWI performed better than normal bic-tcp.
