Earliest Deadline

Today, due to recent advances in wireless technology, new products using wireless sensor networks are being employed. However, despite the excitement surrounding wireless sensor networks, it is not immune to the problem of energy consumption. To overcome this deficiency and enhance the real time aspect, a growing interest lies in the implementation of an “Earliest Deadline First” (EDF) scheduler. Thus, in this paper, the authors establish a management policy of periodic tasks that is preemptive, multiprocessor, and dynamic. The authors implement a real-time scheduling policy as a part of a user-level threads package under the Linux operating system as Linux does not support EDF. Furthermore, this paper describes the technique of the EDF scheduler and how it can yield to significant power savings.
