Modeling and Performance Evaluation with WAP system

As WAP net, the anytime and anywhere wireless manner to access internet, used by more and more clients, it is essential to evaluate the WAP systems' performance during its design phase for proving they have adequate capacity to support potential load. In this paper we use Performance Evaluation Process Algebra (PEPA) to evaluate a typical WAP system's performance. The approach is more convenient, flexible, and lower cost than the former simulation method which needs develop special hardware and software tools. Moreover, we can easily analysis how changes in performance depend on changes in a particular parameter by supplying ranges for parameter rate values.
