Development of An Enhanced Load Balancing Algorithm for Heterogeneous Distributed System Environment

In a Heterogeneous Distributed System Environment (HDSE), a load balancing algorithm ensures even distribution of tasks between the various systems and the appropriate server for each of the different client request, based on server capacity, current connection time and IP address. This is to avoid uneven distribution of tasks and thereby overloading some servers to the detriment of others. An enhanced heterogeneous load balancing algorithm was developed to address the shortcomings observed in the conventional load balancers to improve on the performance of the job response time, throughput, and turnaround time. The developed load balancing algorithm was executed using scheduling techniques: the Weighted Round Robin (WRR) and Least Connection algorithms. The load balancing algorithm was coded in C-Language with in-built functions of the C-Library and the Performance Evaluation Test (PET) was carried out using Average Turnaround Time (ATAT}, Average Waiting Time (AWT) and Throughput (ThP) The results of the test demonstrated an improved performance on conventional load balancing algorithm in a HDSE.
