Abstract
Transmission Control Protocol (TCP) is a fundamental protocol in the TCP/IP Protocol Suite.TCP was well designed and optimized to work over wired networks where most packet loss occurs due to network congestion. In theory, TCP should not care whether it is running over wired networks, WLANs, or Mobile Ad hoc Networks (MANETs). In practice, it does matter because most TCP deployments have been carefully designed based on the assumption that congestion is the main factor of network instability. However, MANETs have other dominating factors that cause network instability. Forgetting the impact of these factors violates some design principles of TCP congestion control and open questions for future research to address. This study aims to introduce a model that shows the impact of MANET factors on TCP congestion control. To achieve this aim, Design Research Methodology (DRM) proposed by BLESSING was used as a guide to present this model. The proposed model describes the existing situation of TCP congestion control. Furthermore, it points to the factors that are most suitable to be addressed by researchers in order to improve TCP performance. This research proposes a novel model to present the impact of MANET factors on TCP congestion control. The model is expected to serve as a benchmark for any intended improvement and enhancement of TCP congestion control over MANET.

Summary
Applications, such as an emergency service at a disaster site, military operations in a remote area, business. Transmission Control Protocol (TCP), is a de-facto standard protocol that provides reliable, endto-end and connection-oriented data delivery over connect to each other using a wireless channel unreliable networks (Boukerche, 2008), forming a temporary network without 2005). It is the dominant protocol used on the Internet the aid of fixed infrastructure (Sarkar et al, 2007). MANET has received considerable attention due to the attractive properties of building a network on-the-fly with ease, speed of deployment and today, since it is responsible for the transmission of around 90% of Internet traffic (Mark and Aaron, 1999). TCP as an efficient transport protocol has several responsibilities, the main onesbeing to avoid congestion in decreased dependence on infrastructure.
