Task energy and real time system scheduling

In this paper we discuss the real time system and its scheduling issues. We put focus on what is real time system? It's scheduling categories and criteria. The role of task energy in the scheduling algorithm and type of the energy recently demanded in the currently real time system, also several scheduling algorithm and their comparison. We present our energy driven scheduling algorithm and compare it with existing algorithm. The ambient energy taken in to the consideration here from sun light using solar. In terms of demonstration of scheduling algorithm we implement it for various metrics such as task energy, overhead and success rate.
