Job scheduling technique for infrastructure as a service cloud using an improved league championship algorithm
League Championship Algorithm (LCA) is a sports-inspired population based algorithmic framework for global optimization over a continuous search space first proposed by Ali Husseinzadeh Kashan in the year 2009. A general characteristic between all population based optimization algorithms similar to the LCA is that, it tries to progress a population of achievable solutions to potential areas of the search space when seeking the optimization. In this paper, we proposed a job scheduling algorithm based on an enhanced LCA optimization technique for the infrastructure as a service (IaaS) cloud. Three other established algorithms i.e. First Come First Served (FCFS), Last Job First (LJF) and Best Effort First (BEF) were used to evaluate the performance of the proposed algorithm. All four algorithms assumed to be non-preemptive. The parameters used for this experiment are the average response time, average completion time and the makespan time. The results obtained shows that, LCA scheduling algorithm perform moderately better than the other algorithms as the number of virtual machines increases
