Abstract 

This project work is concerned with application of Petri Net in protocol specification. In this project work, definition of Petri Nets and Protocols are given. The role and importance of formal specification techniques are also discussed. Petri Nets are a graphical tool and could be used for the formal description of the flow of activities in complex systems like protocol. It is gaining popularity in recent years as a tool for the representation of complex logical interactions like synchronization, sequence, concurrency and conflict among physical components or activities in the system. This project work presents a specification of a chosen protocol using Petri Net and implemented the specification using JAVA programming language. Conclusively, Petri net is shown to be 70% better than other formal protocol specification methods.
