Abstract

Transmission Control Protocol (TCP) is the most popular protocol used over the wired and wireless networks, and it still has a practical problem where the congestion control mechanism does not permit the data stream to get complete bandwidth over the existing network links. To solve this problem, many TCP protocols have been introduced with high speed performance. The work provided in this article is based on using the Network Simulator 2 (NS-2) to implement a new proposed TCP called “Sumer” TCP. The proposed TCP is based on the same characterizations of Reno TCP, such as congestion control, sliding window and other Reno mechanisms and features.The process of creating new TCP agent over the platforms of NS-2 requires a lot of modifications, files generation, and agent identification to make the new agent recognizable by NS-2 resources. The proposed TCP is developed for scientist and researchers to be easy for them to add the new mechanisms such as slow-start and congestion avoidance with other extra features. Key words: Transmission Control Protocol (TCP), Sumer TCP, Reno, congestion control, congestion window, NS-2.
