An advanced Task Assignment Model to Optimize Time Cost and Reliability in Distributed Computing Environment

Abstract—The entire system of Distributed Computing Environment (DCE) looks like a centralized system to the user submitting a task. DCE distribute the computational modules of the given task to various processing nodes for their execution in efficient manner. Task assignment in DCE is one of the main and critical activity by matching the task with processor and schedule task processing in order to achieve optimize solution i.e. finding an allocation of the tasks to the processors in such a way where the total execution cost and time are minimized or improve the performance in terms to minimize cost and time and maximize reliability of DCE. In DCE various computational and informational devices are dispersed over a wide geographical area and providing services to clients. In DCE a problem is divided into one or multiple task modules and each of the task modules allocate on available processor for its execution. In cas
