Abstract

Congestion control is a vital issue in computer networks, especially the Internet. It has always been one of the basic subjects in the field of research. According to the increasing number on the Internet users, its function and services, the traffic of the Internet is highly being increased. By developing in technology however, capacity of data transferring is increasing; but all these developments do not guarantee the utilization of the Internet when it faces traffic overload. For this reason, improvement in congestion control mechanism is a matter that guarantees the utilization of the Internet and lost against network overload. We believe that this issue can be evaluated in accordance with the theories in economy science. The main goal of these theories is to maximize public welfare for people in the society. On the other hand, economy is also the best mathematical tool in order to help recognize hidden dependencies among different network demanding. On this base, we have designed an economical system to give initial services for networkers by early servers. In this system, the width of the band needed for each service proposed as goods. Early servers and their contributors play the role of producers, and all the users are consumers. Proposed algorithm is paved in NS-2 simulated networks and has been compared with XCP and TCP algorithms. The results of this simulation show the success of the proposed way in high utilization and less packet losing.
