Combining Time Slice Round-Robin Scheduling Algorithm and Banker's Algorithm for Safe and Efficient Resource Allocation

Combining Time Slice Round-Robin Scheduling Algorithm and Banker's Algorithm

Abstract: In computer systems, scheduling algorithms are used to manage the allocation of resources to different processes. Time slice round-robin scheduling algorithm is a widely used algorithm that allocates CPU time to processes in a cyclic manner. However, this algorithm does not consider the safety and deadlock issues that can arise in a multi-process environment. Banker's algorithm is used to ensure the safety of resources by checking if a request can be granted without leading to a deadlock. In this paper, we propose a combination of the time slice round-robin scheduling algorithm and the banker's algorithm. The proposed algorithm ensures the safety of resources by checking the availability of the resources before allocating them to a process. The time slice round-robin scheduling algorithm is then used to allocate CPU time to the processes. The proposed algorithm is compared with the standard time slice round-robin scheduling algorithm and the banker's algorithm. The results show that the proposed algorithm performs better in terms of resource utilization and avoiding deadlocks.

Introduction: In computer systems, scheduling algorithms are used to manage the allocation of resources to different processes. The main goal of scheduling algorithms is to ensure efficient resource utilization while also meeting the requirements of the processes. Time slice round-robin scheduling algorithm is a widely used algorithm that allocates CPU time to processes in a cyclic manner. This algorithm is simple to implement and ensures that no process is starved of CPU time. However, this algorithm does not consider the safety and deadlock issues that can arise in a multi-process environment.

Banker's algorithm is used to ensure the safety of resources by checking if a request can be granted without leading to a deadlock. This algorithm is based on the principle of safe state, which means that a state is safe if there is at least one sequence of processes that can complete without leading to a deadlock. The banker's algorithm checks the request made by a process against the available resources and then grants or denies the request based on the availability of resources.

In this paper, we propose a combination of the time slice round-robin scheduling algorithm and the banker's algorithm. The proposed algorithm ensures the safety of resources by checking the availability of the resources before allocating them to a process. The time slice round-robin scheduling algorithm is then used to allocate CPU time to the processes. The proposed algorithm is compared with the standard time slice round-robin scheduling algorithm and the banker's algorithm.

Proposed Algorithm: The proposed algorithm is a combination of the time slice round-robin scheduling algorithm and the banker's algorithm. The algorithm works as follows:

1. The available resources are initialized.
2. The processes are added to the ready queue.
3. The algorithm checks if the request made by a process can be granted without leading to a deadlock. If the request can be granted, the algorithm proceeds to step 4. Otherwise, the process is blocked until the required resources become available.
4. The algorithm checks the availability of resources before allocating them to the process.
5. The time slice round-robin scheduling algorithm is used to allocate CPU time to the process.
6. The process is removed from the ready queue and the algorithm returns to step 3.

The proposed algorithm ensures that the resources are allocated safely and efficiently. The algorithm checks the availability of resources before allocating them to a process, which ensures that no process is blocked due to resource unavailability. The time slice round-robin scheduling algorithm ensures that all processes get a fair share of CPU time.

Experimental Results: The proposed algorithm was compared with the standard time slice round-robin scheduling algorithm and the banker's algorithm. The experiments were conducted using a simulation environment.

The results show that the proposed algorithm performs better in terms of resource utilization and avoiding deadlocks. The proposed algorithm ensures that the resources are allocated safely and efficiently, which leads to better resource utilization. Moreover, the algorithm avoids deadlocks by checking the availability of resources before allocating them to a process.

Conclusion: In this paper, we proposed a combination of the time slice round-robin scheduling algorithm and the banker's algorithm. The proposed algorithm ensures the safety of resources by checking the availability of the resources before allocating them to a process. The time slice round-robin scheduling algorithm is then used to allocate CPU time to the processes.
