Abstract :
This paper presents a location tracking system that improves its performance by mitigating the influence caused by the human body of the user being tracked. The presence of such a user will influence the signal path between a body-worn mobile device and a receiving node. This influence will vary with the user´s location and orientation and, as a result, the performance will deteriorate. By making use of the user´s orientation towards the fixed infrastructure nodes, the influence of the body can be explicitly compensated, hereby improving the tracking accuracy. The overall system performance is extensively verified with experiments on a building-wide testbed. Compensating for this human body shadowing results in a relative improvement of 23.6%.
