Multi Task Management Scheduler in Vehicular Cloud Networks --Mahantesh G Kambalimath,Mahabaleshwar S. Kakkasageri. |
Abstract
The main feature of the Vehicular Cloud Networks (VCN) is the mobile nodes (vehicles). Most of the present and almost future vehicles consist of on-board equipment with sufficient resources and theses resources are underutilized. These vehicles are able to process and executes the tasks. As these vehicles process and executes the tasks are also considered as "moving computer". The significance of this research work to utilize the on-board equipment resources. We design the scheduler which schedules the tasks based on the priorities of the local tasks. Scheduler preempts the remote tasks and executes the local tasks which are considered to be high priority. Scheduler agent program running on computing engine (vehicle) to handle task scheduling. Scheduler plans execution along with local tasks, with latter taking higher precedence. Examples of local tasks are air-fuel ratio, monitoring all events on the vehicle, car functions, valve timing variations, idle speed control etc. Scheduler doesn't interfere with execution all local tasks. This is true even when it has scheduled a remote task as it prioritizes local task by switching context of remote task. Remote task resumes execution when local tasks are done. Keywords: vehicular cloud networks, mobile agent, scheduler, task scheduling. ![]() |
