A Method of QoS Measurement of Web Service Based on Service Using Information
Qin Wang · Journal of Northeastern University · 2009
The existing measuring methods of QoS lack versatility because they only take the common attributes of Web service into consideration but neglect the domain attributes.The measurements of QoS are therefore divided into two categories,i.e.,the constrained Web service and unconstrained one with their respective measuring methods proposed.For the constrained QoS measurement,an algorithm based on constrained information is proposed.As for the unconstrained QoS measurement,the proposed algorithm can adjust automatically the QoS indices and its corresponding coefficients through analyzing service using information.The implemented platform and analysis of experimental results are provided,with which the applicability and effectiveness of the method proposed are verified.
