Malha de rede sem fio como suporte para ambiente parcialmente ubíquo

Abstract

This study aims to simulate a wireless mesh network that provides connectivity to a ubiquitous environment. The research is due the lack of a specific network and has low cost to support ubiquitous computing. In the simulation, we analyzed the constant connectivity requirements and mobility are two of the main requirements needs to support and create a ubiquitous environment. In simulation, set that constant connectivity linked is always to mobility. Is expected that the outcome of this academic work may be useful for studding and simulating ubiquitous environments. For the scenario, testing created was a wireless mesh network topology running the Hybrid Wireless Mesh Protocol. The simulation environment used the Network Simulator 3 and Bonnmotion to support mobility. In NS3, there are no modules to simulate a network of this magnitude and complexity to perfection, but it can create a network with characteristics similar to real network that generate the results necessary to satisfy the purpose of this work. The problems encountered in the creation of this work were the limitations of the simulator relative to the transparent connection of the mobile user. Validation tests were based on metrics: the mobile node on the network connection time, simulation time, switching the connection packages exchange, distance traveled by the mobile user. Our results were inserted on the following a statistical basis for analysis. The tests showed that the simulated network can offer constant connection and mobility necessary to create a ubiquitous environment.
