Design and Implementation of Software-Based Simulator for Performance Evaluation of Transmission Protocol

We propose a method of software-based transmission protocol simulation for the establishment of ubiquitous infrastructure as a method of securing reliability of a ubiquitous sensor network (USN), which is an important element of ubiquitous infrastructure establishment. For this, we designed a transmission protocol network performance measurement simulator. The network simulator was simplified and, thus, could be used for all types of protocol tests. It enabled transmission control protocol (TCP) and user datagram protocol (UDP) transmission and reception regardless of the number of times of transmission and reception. In addition, we implemented an independent network simulator on a platform that enabled transmission at predetermined intervals according to the number of times of transmission and provided the function of randomly transmitting a defined message.
