Study on the Mobile LBS Development Model

Mitigación de la Condición NLOS para Sistemas de Posicionamiento de Suscriptor Móvil usando Ponderación de Medidas y Restricciones Geométricas

“…In fact, LBS are a key piece of this dynamism, not just because LBS are hunger of more resources from network devices but also because they take advantage of the virtuosities of new communication technologies to construct new possibilities of relation among users, between users and service providers, and also between providers and third parties such as contents' providers. Neither it is strange that all these systems' elements are object of permanent research and keep in permanent revision [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. This paper focuses in network based positioning technologies and particularly in the mitigation of an important issue, which strongly degrades the accuracy of the subscriber due to the specific propagation conditions of the wireless signals, known as Non Line Of Sight (NLOS) condition.…”

Indoor Pedestrian Positioning Tracking Algorithm with Sparse Anchor Nodes

“…With the improvement of communication technology, location-based service (LBS) [1] has drawn more and more attention and will have a significant impact on human life and work. For example, the use of Global Positioning System (GPS) and electronic map in vehicle navigation and the use of intelligent mobile phone help people outside to find their place and route.…”
