Uma metodologia de localização Indoor híbrida para sistemas móveis

Abstract

In recent years technological development has allowed the emergence of several applications and location services, with emphasis on localization solutions in indoor environments (tracking of objects, assets and people, precision marketing, security and others). It is known that traditional localization solutions, such as the Global Positioning System (GPS) do not present satisfactory results for indoor scenarios and that other solutions already exist in the literature. On this work, a new solution is provided to the indoor location problem based on multiplicity of communication sources and protocols, trilateration method, motion tracking, inertial sensors and algorithms for mitigation of signal propagation misrepresentations with the intention increase the accuracy of the solution. Results indicated the feasibility of the proposal with average errors of 1,224 meters in typical scenarios of densely populated buildings.
