Expand Study of Protocol Based on NS-2 No Need for Packet Header Methods

The enduring changes of operate demands in network stimulate the production & development of new protocols and new algorithms. But designing and calculating these protocols and algorithms concern many problems. Although it is valuable of the practical experiment in the real circumstance like laboratory and test bed, they lack proper flexibility and expansibility. Under this circumstance, Network simulators becomes one of the important methods of experiment and study. NS-2 is a strongly functional network simulator software, which applies to all kinds of simulate of network study above network hierarchy. This paper takes TCPW as the study object,through the improvement and perfection of its inner contained algorithms and protocols, no need for new packet header, to carry out the expanded study and realization of NS-2.
