Modeling, verifying and testing the mobility management in the mobile IPv6 protocol

Mobility systems are complex. They are composed of several distributed, heterogeneous and, obviously, mobile components. The paper deals with the modeling, verification and testing of mobility protocols using the SDL approach. A well suited model is proposed to handle the component-based nature of mobile systems. We show that the chosen model allows the verification of mobility mechanisms and the performance of conformance and interoperability testing. The solution suggested to derive the test cases in the new testing language, TTCN-3, is described
