Abstract
In the field of communication safe and reliable transmission of data is extremely important issue. Emergence of computer networks and internet brings a tremendous change in the field of communication. Protocols are the set of rules, which are used for the reliable communication of data .Sliding Window (SW) protocol, is one of the most important protocols that have been used out currently. Various Popular protocols like Transfer Control Protocol (TCP) and High Level Data Link Control Protocol (HDLC) are based on the Sliding Window Protocol. Sliding Window protocol can be subdivided in Stop and Wait, Go Back N and Selective Reject Protocol .This paper deals with the simulation and analysis of the Stop & Wait protocol in MATLAB environment. The designed simulator will perform the basic operation of protocol and provide the direct interface to user to enter the parameter which provide the results in the form of data and graphical plots. The simulator is a tool for demonstrating the various protocols, algorithms and to serve as an aid in the better understanding of the protocols. The challenges of teaching computer networking to large classes can be successfully tackled by the use of an interactive network simulator. Analytical and graphical teaching approach is always very effective and efficient. This paper is small contribution in this direction.
