Genetic Algorithm-Based Dynamic Load Balancing for Server Cluster in Network GIS

In the network geographic information system(network GIS),to improve its quality of service(Qos),we usually use cluster to manager servers,and use load balancing techniques to balance the web loads.We propose a GA-based dynamic load balancing algorithm combined with the existing load balancing methods and the data feather of network GIS.Both the request's content and the state of the server are considered.We also design the ingenious coding and genetic operators of GA accordingly.The experiment's results show that the GA-based load balancing method can reduce response time and bring better service to network GIS compared with other common algorithms.
