Abstract

This paper aims at studying various algorithms for dynamic load balancing pertinent to the significant issues handled by them. When some of the nodes are overloaded and other nodes are moderately or even under loaded, the process of load balancing redistributes the work load. By this means, utilization of resources and response time can be enhanced. Numerous algorithms are available for dynamic load balancing. Based on the current position of the system, these algorithms make the load balancing decisions. Several factors such as performance indices, load estimation, amount of information exchanged among nodes, load levels comparison, system stability, choosing remote nodes, and estimation of resource requirements should be taken into account. Consideration of these factors contributes a lot for developing an efficient dynamic load balancing algorithm. Relevant to the design of efficient algorithms for dynamic load balancing, this work brings into limelight the aforesaid factors.
