Abstract:
The wireless computer network technologies have considerably evolved in the last decade
and, as such, do represent an important technical alternative for local area networking. The IEEE (Institute of Electrical and Electronics Engineers), through the development of the IEEE 802.11 standard project, is the main institution promoting the use and boosting this new technology for networking in the global scenario. Development of computer network systems typically requires the use of tools like simulators. These tools are mainly used to study and analyze system performance in relation either to the available technological alternatives or with respect to the expected system behavior. This Master Degree Dissertation presents the software components specification that could be used in the construction of simulation tools for computer networks based on the IEEE 802.11 standard. The specification presents the resources for the analysis and project phases according with the development process, as proposed by Craig Larman. UML (Unified Modeling Language) is used as modeling resource. The detailed project presented is based on event oriented JavaBeans components. The proposed components represent the essential elements for modeling both wireless ad hoc and multi-cell networks. The proposed components are: traffic source, source station, link, access protocol, source access point, distribution system, destination access point, destination station
and sink. The software components specification presented may be easily reused for
constructing new simulation tools or, alternatively, for extending available functionalities in
existing simulation tools.
