MODIFIED APPROACH FOR SECURING REAL TIME APPLICATION ON CLUSTERS

In today arena security critical real time applications running over clusters are growing very rapidly. As an application runningon clusters demand both timeliness and security thus, an efficient scheduling algorithm is needed that have better performance interms of both number of task accepted and security value received. This paper modifies the security aware scheduling approach[5] by utilizing the concept of task criticality and adaptive threshold value. Also, this paper discus the system architecture used,mathematical model, lemmas and modified scheduling approach. Further, simulation studies have been carried out in MATLAB(module for Real-time) to measure the performance of modified approach. The modified approach is applicable over wide rangeof application differing in there requirement and have better performance.
