Abstract:

In order to get proper deployment locations for hot grid services in pursuit of the shortest average response time for clients, an algorithm based on election and region combination was proposed. The distribution and access frequency of clients, network delay and the process performance of grid nodes were considered. During the initial phase, the topology of grid is divided into multiple regions, then one of these regions is eliminated through election, and the remains are readjusted. After several iterations, the deployment locations are found out. Simulations show that the algorithm can get optimal resolution approximately.
