Automatic Network Protocol Synthesis from UML Sequence Diagrams

This paper presents a methodology to automatically generate SystemC protocol implementation, starting from its specification given through UML sequence diagrams. The methodology merges such diagrams into a single one, which is then used to generate the SystemC code. Two algorithms are proposed for the merging and refinement step, respectively. SCNSL network simulator is exploited to simulate the generated code in a complete network scenario. As case study, the methodology is applied to sequence diagrams contained into IEEE 802.15.4 protocol standard specification.
