A Tricky Task Scheduling Technique to Optimize Time Cost and Reliability in Mobile Computing Environment

Abstract

Mobile Computing Environment (MCE) consisting portable computing devices interconnected by wireless medium, are increasingly being used in many area of science, business and education etc nowadays. It is the computation made over physical mobility. MCE facilitate the user to perform a task from a distant place from the device. This provides flexible communication between user and continuous access to networked services. Mobile computing shares many features with distributed computing as the application runs in MCE executes in distributed manner i.e. an application is combination of multiple tasks and these task schedule on the available resources to be execute. The performance of an application is depending on task scheduling technique in MCE. Task scheduling technique consist in finding an allocation of the tasks to the processors such that the total execution cost and time are minimized or processing reliability is maximized. So the ultimate objective of finding task scheduling technique is to improve the performance in terms to minimize cost and time and maximize reliability of MCE. In MCE an application can be seen as one or multiple task modules and each of the task modules allocate on available processor for its execution. Therefore, in this paper, the problem of scheduling the tasks in mobile computing environment is explore with objectives to minimize processing cost, processing time or maximize the processing reliability through a new task scheduling technique to optimize performance in MCE. The nature of the assignment will be static.
