Transmission Control Protocol (TCP) provides reliable transport services for Internet applications. Broadband Geostationary Earth Orbit (GEO) satellite networks play an important role in providing Internet access and network connectivity. They are characterized by long propagation delays and high bit error rates, which negatively affect TCP performance. The paper proposed a modification of TCP named TCP with adaptive delay and loss response algorithm (TCP-ADaLR) that improves TCP performance in broadband GEO satellite networks. This paper describes the TCP-ADaLR algorithm and its OPNET implementation. It evaluates and compare the performance of TCP-ADaLR, TCP SACK, and TCP NewReno, with and without delayed acknowledgment.
