Hybrid Metaheuristic Algorithm based Task Scheduling in Cloud Computing

PhD Research Topics for Hybrid Metaheuristic Algorithm based Task Scheduling in Cloud Computing

A hybrid meta-heuristic algorithm for task scheduling in cloud computing combines two or more/multiple meta-heuristics to perform better than a single meta-heuristic. The goal of task scheduling in cloud computing is to allocate tasks to available resources in the cloud, such as virtual machines, to meet certain objectives, such as minimizing the completion time, maximizing resource utilization, or minimizing energy consumption.

The hybrid meta-heuristic algorithm combines the strengths of numerous meta-heuristics to address the challenges and limitations of each meta-heuristic. It typically involves several phases: initialization, solution generation, evaluation, and improvement. During the initialization phase, the algorithm generates a population of initial solutions using one or more meta-heuristics.

During the solution generation phase, the algorithm generates new candidate solutions using a combination of meta-heuristics. During the evaluation phase, the algorithm assesses the quality of the candidate solutions using a suitable fitness function. The algorithm chooses the best solutions during the improvement phase and applies improvement operators, such as mutation and crossover, to generate better solutions.

The hybrid meta-heuristic algorithm repeats these phases until a termination criterion, such as a maximum number of iterations or a satisfactory solution quality, is met. The algorithm outputs the best solution as the final schedule for task execution in the cloud.

 •  Complex constraints: A hybrid algorithm can better handle complex constraints and requirements, such as conflicting objectives and resource constraints, than a single meta-heuristic.
 •  Increased scalability: A hybrid algorithm can scale better to handle larger and more complex task scheduling problems in cloud computing than a single meta-heuristic.
 •  Faster convergence: The hybrid algorithm can exploit the strengths of different meta-heuristics to find the optimal solution more quickly.
 •  Effective exploration and exploitation: The hybrid algorithm can effectively balance exploration and exploitation of the solution space, leading to a more efficient search.

Disadvantages of Hybrid Metaheuristic Algorithm-based Task Scheduling in Cloud Computing


 •  Complexity: Hybrid metaheuristic algorithms often involve multiple heuristics, increasing the algorithm-s complexity and making it more difficult to understand and implement.
 •  Local Minima: Hybrid metaheuristics are prone to get stuck in local minima, resulting in sub-optimal solutions.

 •  Robustness: Hybrid metaheuristics may not be robust to changes in the environment or input data, which can result in poor performance and sub-optimal solutions.

Challenges in Hybrid Metaheuristic Algorithm-based Task Scheduling in Cloud Computing


 •  Parameter Selection: Selecting the appropriate parameters for the hybrid metaheuristic algorithm can be challenging and require multiple trials to determine the optimal settings.
 •  Balancing Exploitation and Exploration: Hybrid metaheuristics must balance the exploitation of the best solution found so far with the exploration of other possible solutions, which can be difficult to achieve.
