Research on trustworthiness-based grid resource selection optimized algorithm

Abstract

Resource selection is the central part and a prime concern of Grid research. This paper analyses the character of grid, taking into account the performance of algorithm and frequency used in grid domain. The reputation is calculated according to history experience and immediate situation. Our algorithm has dynamic and overall situation in resource selection, considering the trust for history accumulation, introducing into the function depend on time, It provides a method for selecting the value of recommend trust relationship in Grid resource selection, and suffices requirement of user and provider. Experimental results show that the model is exact and robust. © 2011 Springer-Verlag Berlin Heidelberg.
