Um problema crítico com sistemas de posicionamento baseados em LAN sem fio é a degradação na precisão da estimativa de posição devido à variação complexa na intensidade do sinal recebido, que se origina na natureza do canal sem fio subjacente. Lidar com essa variação de forma eficaz é essencial para a criação de sistemas práticos de posicionamento baseados em LAN sem fio. Neste artigo, propomos um mecanismo colaborativo para correção de erros de estimativa de posição. O principal objetivo é auxiliar os usuários na correção manual de erros de estimativa, fornecendo acesso a um conjunto compartilhado de informações acumuladas sobre correções feitas por muitos outros usuários. Em particular, o mecanismo foi concebido para permitir que qualquer grupo de utilizadores desenvolva colaborativamente este conjunto de informações. Finalmente, avaliamos a eficácia do mecanismo proposto através de experimentos. Os resultados confirmam que o mecanismo proposto pode fornecer correção eficaz de erros de estimativa em um ambiente realista.

Abstract: A critical problem with wireless LAN-based positioning systems is the degradation in position estimation accuracy due to complex variation in the strength of the received signal, which originates in the nature of the underlying wireless channel. Handling such variation effectively is essential for the creation of practical wireless LAN-based positioning systems. In this paper, we propose a collaborative mechanism for correcting position estimation errors. The main objective is to assist users in correcting estimation errors manually by providing access to a shared body of accumulated information on corrections made by many other users. In particular, the mechanism is designed to enable any group of users to collaboratively build upon this body of information. Finally, we evaluate the effectiveness of the proposed mechanism through experiments. The results confirm that the proposed mechanism can provide effective estimation error correction in a realistic environment.
