| Summary: | The number of web services made available on the Internet is progressively increasing, yielding more and more services performing similar functions. Those competing same
functionality web services create an issue on selection criteria,namely, which service should be selected? Why? One of the most substantial selection factors is the Quality of service (QoS). This paper analyses the QoS characteristics that were most commonly used to evaluate web services in order to determine the QoS characteristics that are probable in generating an optimum selection criteria for the competing web services. The selected QoS criteria are analyzed in terms of their importance in order to determine the mandatory, highest and lower priority QoS criteria. Such prioritization is reflected in the assignment of different weight values when developing an optimum web service composition. Justitications for prioritizing the selected QoS criteria are tabled with the intention to assist clients in deciding on which web services to
select, and predetermined those selection criteria in their
requirements. |
