Real-time scheduling theory has shown an impressive evolution in the past few years. As a consequence of the intensive research done in this area a lot of new scheduling policies had been proposed to date. Nevertheless, just a few of such scheduling policies are available in existing Real-Time Operating Systems (RTOS). In this paper, we describe Realtss, an open source realtime scheduling simulator which is suited to simulate real-time scheduling algorithms without the need of implement them in a RTOS. Realtss is an invaluable teaching and researching tool since existing and new real-time scheduling policies can be easily evaluated.

Increasing Deadline Meeting Rate (DMTR) during overload is a concern of Soft Real Time (SRT) Scheduling. Here we present our non-preemptive non-resource constraint scheduling model implemented on an open source discrete event simulator named OmNET. The model is simple, yet it fulfill the simulation purpose, which mimics execution of jobs schedule under non-preemptive and non-resource constraint system within usual real time timing parameters namely release time, execution time, deadline and period. We show that OmNET is capable to be used as a real time scheduling simulator. Along with, we also present the approach we undertook to design our novel SRT scheduling algorithm. The simulation result presented here shows the effect of Deadline Tolerance (SRT parameter) and Deadline size on DMTR. We conclude that our algorithm named gutEDF could produce higher DMTR as compared to Earliest Deadline First (EDF) algorithm during overload while maintaining optimum performance under normal load.

Simulation based studies are inevitable in the field of real time scheduling, due to the difficulty in remodeling the existing Real Time Operating System (RTOS) to incorporate new scheduling policies. This paper presents a real time simulator-ERTSim, which can be used for solving scheduling problems in the real time domain. The features of ERTSim includes: Graphical User Interface (GUI), synthetic task generation algorithms, modules for feasibility tests, implementation of task scheduling algorithms and generating execution traces for visual understanding. ERTSim is developed using structured C and C++ class functions.
