Reliability and latency calculation in grid computing systems

Grid Computing Systems (GCS) have been suggested as an effective technology in geographically distributed resource coupling for applications that require large space for computations and resources. Reliability has proved to be one of the most important criteria in grid systems. In such systems, dynamic access to the required resources is complex, and therefore achieving reliability tends to be very difficult. In this paper we propose an algorithm to estimating reliability of grid system and latency time. The algorithm is based on Graph theory and Bayesian theory. Proposed algorithm considers the transmission rate of data between nodes through links to estimate the reliability of involved nodes and links which requires high reliability and less latency for using of several identical resources and it is appropriate for GCS.
