Especificação e implementação de componentes para modelar redes locais sem fio ad hoc padrão IEEE 802.11.

Abstract

This Master Dissertation presents the specification and the implementation of software components aiming to facilitate the building level high simulation tools that are applied in both modeling and performance evaluation of wireless ad hoc networks following IEEE 802.11 standard. The utilization of component-oriented software development approach allows new applications to be constructed visually by means of a set of components linked with each other, using a visual development environment. The software components presented in this Dissertation represent essential elements for the modeling of wireless ad hoc networks IEEE 802.11 standard (frame source, hosts - with the implementation of the access protocol CSMA/CA, link and sink). In order to validate the reuse of the components ad hoc networks, a simulation environment inserting those components was built. This environment explores the software reuse including other essential components to the event-driven simulation environment, such as: simulated clock, random value generators, event list, performance measures processor. As a study case, a simulator of wireless ad hoc networks IEEE 802.11 standard, with graphic user interface was built. It is pointed out that the users of the presented components are developers of simulation tools for wireless ad hoc networks, that can build specific simulators, simply configuring and linking components, extending theirs functionalities, or even, adding new components to the development environment.
