QoS-Aware Service Selection based on Genetic Algorithm.
Hadjila Fethallah, Amine Chikh, Mohammed Dali Yahia · 2011
Abstract — The web service selection is a primordial step in the support of dynamic compositions, in fact, the presence of a set of services that provide the same functionality (inputs/outputs), but differ in QOS criteria, obliges us to adopt an optimization strategy in order to select the best ones. Several approaches of various natures (mono-objective, multi-objective...) were proposed to solve this problem. In this paper we propose a genetic algorithm which handles a single objective function and a set of global constraints that must be fulfilled. The obtained results are encouraging and merit to be continued. Keywords- web services; combinatory optimization; genetic algorithms;qualiy of service;service oriented architecture.
