A Dynamic Ranking Value Guided Scheduling Mechanism (RVGSM) for Mobile Grid

Mobile computing is the new trend in the computing systems. The traditional computing systems don\´t consider the special criteria of the mobile resources (definitely connection stability). The originality of this paper is to investigate a dynamic scheduling mechanism which considers the mobile devices as resources. In the proposed mechanism assigning a given task to the available ranked resource is done dynamically by using two types of schedulers (dedicated and opportunistic). Improving the performance of these algorithms is achieved by using powerfully source evaluation algorithm, so the overall performance of the mobile computing environment will increase. In the proposed mechanism "self ranking algorithm (SRA)", which distributing some of the functions of the access point among the available attached mobile devices, is employed. The proposed mechanism is experimentally validated for the various distribution forms of the incoming jobs. Experimental results depict that, embedding of SRA within the proposed mechanism has a great impact in improving the system load balancing and increase the system throughput by reducing the required scheduling time
