Abstract: The ad hoc network is a continuously self-configuring and decentralized network where nodes communicate with each other without the fixed network infrastructure or centralized administration. TCP (Transmission Control Protocol) is a connection-oriented transport protocol that provides a reliable exchange of data streams. Implementation of TCP in wireless networks has many challenges such as the issues of the efficiency and TCP fairness problem. The fairness means that network nodes (users or applications) are receiving a fair share of overall resources. In this paper, we study the problem of maintaining the fairness for TCP connections in ad hoc networks. Our research has been made to present the TCP fairness problem in MANET (ad hoc mobile networks) while considering the sending and receiving of traffic. Achieving fairness in these networks is a challenge due to specific characteristics of an ad hoc environment and it is necessary to adapt TCP for ad hoc networks. The primary goal of this paper is to present fairness in ad hoc networks using combinations of different TCP variants and routing protocols. We evaluated the results of our research by using the proper simulation method.
